Program description Print a Square where each row contains one number:-

In this program, we will first take the input side of the square by the user. Then we will print the square using the for-loop. Printing that pattern filled with numbers in each row contains one number. The below is an example of the square program code.

Program Code:-

#include<stdio.h>
 
int main()
{
    //declaring the required variables for the program
    int i, j, Side;
    
    //Taking the input side of the square
    printf("Please Enter Any Side of a Square : ");
    scanf("%d", &Side);
    //Generating the square from the code
    for(i = 0; i < Side; i++)
    {
    	for(j = 0; j < Side; j++)
		{
		    //Printing the numbers to create the square.
           	printf("0");
        }
        printf("\n");
    }
    return 0;
}

#include<stdio.h>

int main()

{

//declaring the required variables for the program

int i, j, Side;

//Taking the input side of the square

printf("Please Enter Any Side of a Square : ");

scanf("%d", &Side);

//Generating the square from the code

for(i = 0; i < Side; i++)

{

for(j = 0; j < Side; j++)

{

//Printing the numbers to create the square.

printf("0");

}

printf("\n");

}

return 0;

}

  	//Taking the character that will be replaced.
  	printf("\n Please Enter the New Character :  ");
  	scanf("%c", &Newch);
  	//Replacing the characters
  	for(i = 0; i <= strlen(str); i++)
  	{
  		if(str[i] == ch)  
		{
  			str[i] = Newch;
 		}

str[i] = Newch;

}

//Printing the output string after the replacement

printf("\n The Final String after Replacing All Occurrences of '%c' with '%c' = %s ", ch, Newch, str);

printf("\n Please Enter the New Character : ");

scanf("%c", &Newchr);

//Replacing the characters in the string.

for(i = 0; strg[i] != '\0'; i++)
