C Exercises: Print 3 numbers in a line, starting from 1 and print n lines

C Basic Declarations and Expressions: Exercise-41 with Solution

Write a C program to print 3 numbers in a line, starting from 1 and print n lines. Accept number of lines (n, integer) from the user.

Pictorial Presentation:

Sample Solution:

C Code:

#include <stdio.h>
int main() {
	int a, i, j = 1, x = 0;
	printf("Input number of lines: ");
	scanf("%d", &a);
	for(i = 1; i <= a; i++) {
		while(x < 3) {
			printf("%d ", j++);
			x++;
		}
		x = 0;
		printf("\n");
	}
	
	return 0;
}

Sample Output:

Input number of lines: 5                                               
1 2 3                                                                  
4 5 6                                                                  
7 8 9                                                                  
10 11 12                                                               
13 14 15
