Question

C program

1. Write a function which draws a line of n asterisks, n being passed as a parameter to the function. Write a driver program (a program that calls and tests the function) which uses the function to output an m x n block of asterisks, m and n entered by the user.

Answer 1

#include<stdio.h>

void drawLine(int n){
   int i = 0;
   while(i<n){
      printf("*");
      i++;
   }
   printf("\n");
}

int main() {
   int n,m,i,j;
   
   printf("Enter value for m: ");
   scanf("%d",&m);
   
   printf("Enter value for n: ");
   scanf("%d",&n);
   
   for(i=0;i<m;i++){
          drawLine(n);
   }
   return 0;
}

Output:

Enter value for m: 5 Enter value for n: 10 tttttttttt tttttttttt tttttttttt tttttttttt + + + + + + + + + +
