C Exercises: Reads the side of a square and prints square using hash (#) character

C Basic Declarations and Expressions: Exercise-80 with Solution

Write a C program that reads the side (side sizes between 1 and 10 ) of a square and prints square using hash (#) character.

Sample Input: 10

Sample Solution:

C Code:

#include<stdio.h>
int main()
{
    int size, i, j; // Declare variables for size and loop counters
    
    // Prompt user for the size of the square
    printf( "Input the size of the square: \n" );
    scanf( "%d", &size );
    
    // Check if the size is within the valid range
    if(size < 1 || size > 10) {
        printf("Size should be in the range 1 to 10\n"); // Print error message
        return 0; // Exit the program
    }
    
    // Loop for rows
    for(i=0; i<size; i++) {
        // Loop for columns
        for(j=0; j<size; j++) {
            printf(" #"); // Print a space and a #
        }
        printf("\n"); // Move to the next line after completing a row
    }

    return 0; // Indicate successful program execution
}

Sample Output:

Input the size of the square: 
 # # # # # # # # # #
 # # # # # # # # # #
 # # # # # # # # # #
 # # # # # # # # # #
 # # # # # # # # # #
 # # # # # # # # # #
 # # # # # # # # # #
 # # # # # # # # # #
 # # # # # # # # # #
 # # # # # # # # # #
