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.
