# Program for Pascal Triangle in C and C++

Here I have shared simple program for pascal triangle in C and C++.

Basically Pascal’s triangle is a triangular array of binomial coefficients. An example for how pascal triangle is generated is illustrated in below image. If you have any doubts then you can ask it in comment section.

Each number is the sum of the two directly above it.

## Program for Pascal Triangle in C

```#include<stdio.h>

//function to calculate factorial
long fact(int x)
{
int i;
long f=1;

for(i=1;i<=x;++i)
{
f=f*i;
}

return f;
}

int main()
{
int i,j,k,n;
printf("How many lines? ");
scanf("%d",&n);

for(i=0;i<n;++i)
{
//loop to print spaces at starting of each row
for(j=1;j<=(n-i-1);++j)
{
printf(" ");
}

//loop to calculate each value in a row and print it
for(k=0;k<=i;++k)
{
printf("%ld ",fact(i)/(fact(i-k)*fact(k)));
}

printf("\n");	//print new line after each row
}

return 0;
}```

## Program for Pascal Triangle in C++

```#include<iostream>

using namespace std;

//function to calculate factorial
long fact(int x)
{
int i;
long f=1;

for(i=1;i<=x;++i)
{
f=f*i;
}

return f;
}

int main()
{
int i,j,k,n;
cout<<"How many lines? ";
cin>>n;

for(i=0;i<n;++i)
{
//loop to print spaces at starting of each row
for(j=1;j<=(n-i-1);++j)
{
cout<<" ";
}

//loop to calculate each value in a row and print it
for(k=0;k<=i;++k)
{
cout<<fact(i)/(fact(i-k)*fact(k))<<" ";
}

cout<<"\n";	//print new line after each row
}

return 0;
}```

Output

1. palindrome nos. are those nos. whose reverse is same ….crazy programmer is my program right … i mean can i get full marks for it in exam as it works.. |
