用C语言编写代码输出100以内的质数

以下是用C语言编写的输出100以内质数的代码：

#include <stdio.h>

int main() {
    int i, j, is_prime;
    
    printf("Prime numbers between 1 and 100:\n");

    // Check every number between 2 and 100
    for (i = 2; i <= 100; i++) {
        is_prime = 1; // Assume the number is prime
        
        // Check if the number is divisible by any number between 2 and itself
        for (j = 2; j < i; j++) {
            if (i % j == 0) {
                is_prime = 0; // Number is not prime
                break;
            }
        }
        
        // If the number is prime, print it
        if (is_prime) {
            printf("%d ", i);
        }
    }
    
    return 0;
}

运行以上代码，会输出如下内容：

Prime numbers between 1 and 100:
2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97
