Write a C program that reads two integers p and q, prints p number of lines in a sequence of 1 to b in a line.

Sample Solution:

C Code:

#include <stdio.h>
int main() {
    int x, y, i, j, l;

    // Prompt for user input
    printf("Input number of lines: ");
    scanf("%d", &x);
    printf("Number of numbers in a line: ");
    scanf("%d", &y);

    // Loop to generate the pattern
    for(i = 1, l=1; i <= x; i++) {
        for(j = 1; j <= y; j++) {
            printf("%d ", l);		
            l++; 
        }
        printf("\n");
    }

    return 0;
}

Sample Output:

Input number of lines: 5                                               
Number of numbers in a line: 6                                      
1 2 3 4 5 6                                                            
7 8 9 10 11 12                                                         
13 14 15 16 17 18                                                      
19 20 21 22 23 24                                                      
25 26 27 28 29 30
