Answer 1

Code :

#include <stdio.h>

int main()
{
    double ans = 10.0 + 2.0 / 3.0 - 2.0 * 2.0;
    printf("ans = %f",ans);

    return 0;
}

Explaination : Order of precedence

* / %	Multiplication/division/modulus	left-to-right
+ -	Addition/subtraction	left-to-right

Step 1 : 10.0 + 0.66667 - 2.0 * 2.0

Step 2 : 10.0 + 0.66667 - 4.0

Step 3 : 10.66667 - 4.0

Step 4 : 6.66667

Result :
