C Exercises: Compute the sum of the two given integers. If the sum is in the range 10..20 inclusive return 30

C-programming basic algorithm: Exercise-17 with Solution

Write a C program to compute the sum of the two given integers. If the sum is in the range 10..20 inclusive return 30.

C Code:

#include <stdio.h>
#include <stdlib.h>

int main(void){
    printf("%d",test(12, 17));
    printf("\n%d",test(2, 17));
    printf("\n%d",test(22, 17));
    printf("\n%d",test(20, 0));
    }   
    
    int test(int a, int b)
         {
          return a + b >= 10 && a + b <= 20 ? 30 : a + b;
        }

Sample Output:

29
30
39
30

Previous: Write a C program to check if a triple is presents in an array of integers or not. If a value appears three times in a row in an array it is called a triple.
Next: Write a C program that accept two integers and return true if either one is 5 or their sum or difference is 5.

C Programming: Tips of the Day

Static variable inside of a function in C

The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().

The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.

The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
