C Program to print Pascal Triangle

C Program to print Pascal Triangle

In this tutorial, we will discuss the concept of  C Program to print Pascal Triangle

In this topic, we are going to learn how  to write a program to print Pascal triangle pattern using number in C programming language

Here, we  use for, while and do-while loops for printing pascal triangle

Display pascal triangle in C using loops

C code display pascal triangle using for loop

In this program, the user is asked to enter number of rows and then it will display pascal triangle number pattern using for loop in C language

Program 1

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int rows,i,j,space,count=1;
    //variable declaration
 printf("Enter the No 0f rows: ");
 scanf("%d",&rows);
 //reading the input for rows
 for(i=0; i<rows; i++){
   for(space=1; space<=rows-i; space++)
   printf("  ");
//print space for left side
   for(j=0; j<=i; j++){
   if(j==0 || i==0)
    count=1;
   else
     count=count*(i-j+1)/j;
     printf("%4d",count);
//print start for pattern
   }
   printf("\n");

}
getch();
    return 0;
}

When the above code is executed, it produces the following result

 

C code display pascal triangle using while loop

In this program, the user is asked to enter number of rows and then it will display pascal triangle number pattern using while loop in C language

Program 2

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int rows,i,j,space,count=1;
 printf("Enter the row for pascal triangle: ");
 scanf("%d",&rows);//Enter number of rows to print pascal triangle
 i=0;
 while(i<rows){//outer while loop  to print space for every line
        space=1;
   while( space<=rows-i){
   printf("  ");//print space
  space++;
   }
j=0;
   while( j<=i){//inner while loop for print pascal triangle
   if(j==0 || i==0)
    count=1;
   else
     count=count*(i-j+1)/j;
     printf("%4d",count);//print pascal triangle
      j++;

   }
   printf("\n");//move to next line
i++;
}
getch();
    return 0;
}

When the above code is executed, it produces the following result

 

C code display pascal triangle using do-while loop

In this program, the user is asked to enter number of rows and then it will display pascal triangle number pattern using do-while loop in C language

Program 3

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int rows,i,j,space,count=1;
    //variable declaration
 printf("Enter the row for pascal triangle: ");
 scanf("%d",&rows);//Enter number of rows to print pascal triangle
 i=0;
do{//outer do-while loop  to print space for every line
        space=1;
   do{
   printf("  ");//print space
  space++;
   }while( space<=rows-i);
j=0;
   do{//inner do-while loop for print pascal triangle
   if(j==0 || i==0)
    count=1;
   else
     count=count*(i-j+1)/j;
     printf("%4d",count);//print pascal triangle
      j++;

   }while( j<=i);
   printf("\n");//move to next line
i++;
} while(i<rows);
getch();
    return 0;
}

 

When the above code is executed, it produces the following result
