C Exercises: Check whether three given integer values are in the range 20..50 inclusive
C-programming basic algorithm: Exercise-8 with Solution
Write a C program to check whether three given integer values are in the range 20..50 inclusive. Return true if 1 or more of them are in the said range otherwise return false.
C Code:
#include <stdio.h>
#include <stdlib.h>
int main(void){
printf("%d",test(11, 20, 12));
printf("\n%d",test(30, 30, 17));
printf("\n%d",test(25, 35, 50));
printf("\n%d",test(15, 12, 8));
}
int test(int x, int y, int z)
{
return (x >= 20 && x <= 50) || (y >= 20 && y <= 50) || (z >= 20 && z <= 50);
}
Sample Output:
1 1 1 0

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().
