Question
Emily is an aspiring programmer on a mission to create a program that acts as a "Square-Free number finder". A square-free number is not divisible by the square of any integer other than 1 for the given number.Write a program that utilizes the goto statement for control flow, and checks if it meets the criteria of being square-free.
Solution
Here is a simple C program that checks if a number is square-free using the goto statement for control flow:
#include <stdio.h>
#include <math.h>
int main() {
int num, i;
printf("Enter a number: ");
scanf("%d", &num);
for(i = 2; i <= sqrt(num); i++) {
if(num % (i*i) == 0) {
goto not_square_free;
}
}
printf("%d is a square-free number.\n", num);
return 0;
not_square_free:
printf("%d is not a square-free number.\n", num);
return 0;
}
This program works by checking if the input number is divisible by the square of any integer from 2 to the square root of the number. If it finds such a number, it uses the goto statement to jump to the not_square_free label, where it prints that the number is not square-free and ends the program. If it doesn't find such a number, it prints that the number is square-free and ends the program.
