Pascal's triangle is a triangular array of the binomial coefficients. In much of the Western world it is named after French mathematician Blaise Pascal . #include<stdio.h> int main() { int i,j,l,binom; printf("enter the no of lines="); scanf("%d",&l); for(i=1;i<=l;i++) { for(j=1;j<=l-i;j++) printf(" "); binom=1; for(j=1;j<=i;j++) { printf("%d ",binom); if(i==j+1) binom=1; else binom=(binom*(i-j))/j; } printf("\n"); } return 0; } OUTPUT- enter the no of lines=6 1 ...
