Biggest of 3 Numbers Using Ternary Operator: C

Lets find biggest of 3 numbers using ternary operator / conditional operator. This program is an example for nested ternary operator.

To find biggest of Three numbers using if-else control structure:
Biggest of 3 Numbers: C

Source Code: Biggest of Three Numbers using ternary operator: C

 
#include < stdio.h >

int main()
{
    int a, b, c, big;

    printf("Enter 3 numbers\n");
    scanf("%d%d%d", &a, &b, &c);

    big = (a>b && a>c) ? (a) : ( (b>c)?(b):(c) );

    printf("Biggest is %d\n", big);

    return 0;
}

Output 1:
Enter 3 numbers
1
2
3
Biggest is 3

Output 2:
Enter 3 numbers
1
3
2
Biggest is 3

Output 1:
Enter 3 numbers
3
2
1
Biggest is 3

In above source code, if a is bigger than b as well as c, then value of a is returned and stored in variable big orelse exression3 gets executed – where we check if b is greater than c.

General Form of Ternary Operator

(expression_1) ? (expression_2) : (expression_3);

expression_1 is a comparison/conditional argument. expression_2 is executed/returned if expression_1 results in true, expression_3 gets executed/returned if expression_1 is false.

Nested Ternary Operator

In our source code, we nest Ternary Operator inside expression3 to find biggest among b and c.

Note:
if ( a > b && a > c ) is true, then value of a will be stored in variable big; else ( b > c ? b : c ) will be evaluated. Here, if value of b is greater than c, value of b will be stored in variable big else value of c will be stored in the variable big.

Biggest of 3 Numbers: C

Lets write C program to find biggest of 3 numbers, using nested if else statement.

Biggest of 3 Numbers Using Ternary Operator: C

C Program To Find Biggest of 3 numbers

 
#include < stdio.h >

int main()
{
    int a, b, c;

    printf("Enter 3 numbers\n");
    scanf("%d %d %d", &a, &b, &c);

    if( a > b && a > c)
    {
        printf("%d is biggest\n", a);
    }
    else
    {
        if( b > c )
        {
            printf("%d is biggest\n", b);
        }
        else
        {
            printf("%d is biggest\n", c);
        }
    }

    return 0;
}

Output 1:
Enter 3 numbers
1
2
3
3 is biggest

Output 2:
Enter 3 numbers
10
18
15
18 is biggest

Here first we check if a is greater than b. If yes, then we display a as big. Else b or c is biggest. So now we check if b is greater than c, if yes, we display b as biggest else c is biggest. Nested if else condition works great for programs like this.

500
550
555
Biggest of 3 number is 555

Biggest of Two Numbers Using Ternary Operator: C

Lets find biggest of 2 numbers using ternary operator / conditional operator.

To find biggest of Two numbers using if-else control structure:
Biggest of Two Numbers: C

Source Code: Biggest of Two Numbers using ternary operator: C

 
#include < stdio.h >

int main()
{
    int a, b, big;

    printf("Enter 2 numbers\n");
    scanf("%d%d", &a, &b);

    (a > b) ? (big = a) : (big = b);

    printf("Biggest of %d and %d is %d\n", a, b, big);

    return 0;
}

Output 1:
Enter 2 numbers
5
6
Biggest of 5 and 6 is 6

Output 2:
Enter 2 numbers
40
15
Biggest of 40 and 15 is 40

 
#include < stdio.h >

int main()
{
    int a, b, big;

    printf("Enter 2 numbers\n");
    scanf("%d%d", &a, &b);

    big = (a > b) ? (a) : (b);

    printf("Biggest of %d and %d is %d\n", a, b, big);

    return 0;
}

Output 1:
Enter 2 numbers
500
900
Biggest of 500 and 900 is 900

In above source code, if a is bigger than b, then value of a is returned and stored in variable big orelse value of variable b is stored in variable big.

General Form of Ternary Operator

(expression_1) ? (expression_2) : (expression_3);

expression_1 is a comparison/conditional argument. expression_2 is executed/returned if expression_1 results in true, expression_3 gets executed/returned if expression_1 is false.

Ternary Operator / Conditional Operator In C

In this video tutorial we will show you how to use Conditional Operator. They are also called Ternary Operators as they take 3 arguments.

General Form of Ternary Operator

(expression_1) ? (expression_2) : (expression_3);

expression_1 is a comparison/conditional argument. expression_2 is executed/returned if expression_1 results in true, expression_3 gets executed/returned if expression_1 is false.

Ternary operator / Conditional Operator can be assumed to be shortened way of writing an if-else statement.

C Program: Ternary Operator / Conditional Operator

 
#include < stdio.h >

int main()
{
    int a = 1, b = 1, c;

    // (expression1) ? (expression2) : (expression3);

     (a+b) ? (c = 10) : (c = 20);

    printf("Value of C is %d\n", c);

    return 0;
}

Output:
Value of C is 10

a+b is 2 which is non-zero, so it is considered as true. So c = 10 gets executed.

 
#include < stdio.h >

int main()
{
    int a = 1, b = 1, c;

    // (expression1) ? (expression2) : (expression3);

     (a-b) ? (c = 10) : (c = 20);

    printf("Value of C is %d\n", c);

    return 0;
}

Output:
Value of C is 20

a-b is 0 which is zero, so it is considered as false. So c = 20 gets executed.

 
#include < stdio.h >

int main()
{
    int a = 1, b = 1, c;

    // (expression1) ? (expression2) : (expression3);

    c = (a+b) ? (10) : (20);

    printf("Value of C is %d\n", c);

    return 0;
}

Output:
Value of C is 10

 
#include < stdio.h >

int main()
{
    int a = 1, b = 1, c;

    // (expression1) ? (expression2) : (expression3);

    c = (a-b) ? (10) : (20);

    printf("Value of C is %d\n", c);

    return 0;
}

Output:
Value of C is 20

C Programming Interview / Viva Q&A: 4 (Logical NOT Operator)

In this video tutorial lets put our understanding of logical NOT(!) operator to test.

Logical NOT(!) Operator in C Program

 
#include < stdio.h >

int main()
{
    int a = 20, b = 30, c;

    if( !(a > b) )
        b = 50;
    c = 70;

    printf("b = %d and c = %d\n", b, c);

    return 0;
}

In this c source code, a is 20 and b is 30. Inside if condition we check if a is greater than b. But a is less than b, so it returns false(0). But we’ve a Logical NOT operator(!) surrounding the false result. So it converts it to true. Hence the next line of code that is, b = 50 gets executed.

So the output is: b = 50 and c = 70
