Following program shows you how to print tables from 1 to 20. In this program we are using for loop to print tables

#include <stdio.h>
int main() {
	for (int table = 1; table <= 20; table++) {
		for (int i = 1; i <= 10; i++) {
			printf("%d * %d = %d \n", table, i, (table * i));
		}
		printf("---------- \n");
	}
}

Output:
