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.
