#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;
}

 
#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.

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;
}

 
#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.

Find Biggest of 3 Numbers: C++

Video tutorial to find the biggest of the three integer numbers in C++, using if-else control statements.

Full Source Code

#include<iostream .h>
#include<conio .h>
 
void main()
{
int a, b, c;
clrscr();
 
cout< <"Enter 3 no\n";
cin>>a>>b>>c;
 
int big;
 
if( a > b )
 big = a;
else
{
 if( b > c )
  big = b;
 else
  big = c;
}
cout< <"\nBiggest is: "<<big;
getch();
}

In this program we get three integer variables from the user.
If value of variable a is bigger, then we store it inside the variable big; else we compare b with c. Now will store the biggest number inside the variable big.
