• Pascal's triangle is a triangular array of the binomial coefficients.

• The program is to display Pascal Triangle for row = 5.

Algorithm:

• Start

• Declare and initialize variables x, y, n, and char c.

• Enter the number of rows.

• Do the following operations in loop.

  • x = 1 to n

  • x++

  • assign char = A

  • y = 1 less than x

  • y++

  • print choose

  • char ++

• Repeat the process to n.

• Print the final required triangle.

• Stop.

Program:

#include<stdio.h>
#include<conio.h>
int main(){
int x, y, n;
char ch;

printf("\n Enter number of Rows:");
scanf("%d",&n);

for(x = 1;x<= n;x++){
printf("\n");
ch = 'A';

for(y = 1;y<=x; y++)  {
printf("%c",ch);
ch++;
}
}
getch();
}

Output:

Enter number of Rows: 5
