Question

C++

Write a program that asks user for a positive integer side length. If they enter an illegal value, they must be prompted to enter a good one until they do. It then displays, using asterisks, a filled diamond of the given side length. For example, if the side length is 4, the program should display:

Answer 1

Code(Text Format):

#include<iostream>

using namespace std;

int main(){

int side;

cout<<"Enter side length: ";

cin>>side;

/*By using this while loop, prompting the user to

enter valid side length.*/

while(side<=0){

cout<<"Please enter valid side length!"<<endl;

cin>>side;

}

//For upper part

/*space variable is used here to denote the spaces

at the beginning of each line of output.*/

int space = side - 1;

for (int i = 0; i < side; i++)

{

//printing beginnig of line spaces

for (int j = 0;j < space; j++)

cout<<" ";

//printing i+1 stars

for (int j = 0;j <= i; j++)

cout<<"* ";

cout<<endl;

space--;

}

//For lower part

space = 1;

for (int i = side-1; i > 0; i--)

{

//printing beginning of line spaes

for (int j = 0; j < space; j++)

cout<<" ";

// Printing i stars

for (int j = 0;j < i;j++)

cout<<"* ";

cout<<endl;

space++;

}

return 0;

}
