Write a C Program to find Cartesian Product of two sets

 What is Cartesian product of two set:-

if set A={1,2} and set B={4,5,6,7}  then Cartesian product of set A and B is :-

          A*B={ (1,4),(1,5),(1,6),(1,7),(2,4),(2,5),(2,6),(2,7) }

#include<stdio.h> int main() { int a[10],b[10],n1,n2,i,j; printf("Enter size of set A\n"); scanf("%d",&n1); printf("Enter element of set A\n"); for(i=0;i<n1;i++) scanf("%d",&a[i]); printf("Enter size of set B\n"); scanf("%d",&n2); printf("Enter element of set B\n"); for(i=0;i<n2;i++) scanf("%d",&b[i]); // logic for cartesian product printf("{"); for(i=0;i<n1;i++) { for(j=0;j<n2;j++) { printf(" (%d %d) ",a[i],b[j]); } } printf("}"); return 0; }
