C program to print Pascal triangle using for
loop
#include<stdio.h>
long fact(int);
int main(){
int line,i,j;
printf("Enter the no. of lines: ");
scanf("%d",&line);
for(i=0;i<line;i++){
for(j=0;j<line-i-1;j++)
printf(" ");
for(j=0;j<=i;j++)
printf("%ld ",fact(i)/(fact(j)*fact(i-j)));
printf("\n");
}
return 0;
}
long fact(int num){
long f=1;
int i=1;
while(i<=num){
f=f*i;
i++;
}
return f;
}
Output:
Enter the no. of lines: 8
