C Exercises: Read an integer and find all its divisor
C Basic Declarations and Expressions: Exercise-47 with Solution
Write a C program that reads an integer and find all its divisor.
Pictorial Presentation:
Sample Solution:
C Code:
#include <stdio.h>
int main() {
int x, i;
printf("\nInput an integer: ");
scanf("%d", &x);
printf("All the divisor of %d are: ", x);
for(i = 1; i <= x; i++) {
if((x%i) == 0){
printf("\n%d", i);
printf("\n");
}
}
return 0;
}
Sample Output:
Input an integer: 45 All the divisor of 45 are: 1 3 5 9 15 45

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().
