Question
In a function two return statements should never occur.
Answer: Option B
#include<stdio.h>
int mul(int, int); /* Function prototype */
int main()
{
int a = 0, b = 3, c;
c = mul(a, b);
printf("c = %d\n", c);
return 0;
}
/* Two return statements in the mul() function */
int mul(int a, int b)
{
if(a == 0 || b == 0)
{
return 0;
}
else
{
return (a * b);
}
}

No, In a function two return statements can occur but not successively.
Example:
#include<stdio.h>
int mul(int, int); /* Function prototype */
int main()
{
int a = 0, b = 3, c;
c = mul(a, b);
printf("c = %d\n", c);
return 0;
}
/* Two return statements in the mul() function */
int mul(int a, int b)
{
if(a == 0 || b == 0)
{
return 0;
}
else
{
return (a * b);
}
}
Output:
c = 0
