C Exercises: Reads two integers p and q, print p number of lines in a sequence of 1 to q in a line

C Basic Declarations and Expressions: Exercise-43 with Solution

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

Sample Solution:

C Code:

#include <stdio.h>
int main() {
	int x, y, i, j, l;
	printf("Input number of lines: ");
	scanf("%d", &x);
	printf("Number of numbers in a line: ");
    scanf("%d", &y);
	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

C Programming: Tips of the Day

Static variable inside of a function in C

The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().

The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.

The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
