C Program to Merge Two Array

#include<stdio.h>

int main()
{
 int a[100], b[100],r[200],i, m, n, pos;
 clrscr();
 /* Reading first array */
 printf("Enter m:\n");
 scanf("%d", &m);
 printf("Enter elements of first array:\n");
 for(i=0;i< m;i++)
 {
  printf("a[%d]=",i);
  scanf("%d", &a[i]);
 }
 /* Reading second array */
 printf("Enter n:\n");
 scanf("%d",&n);
 printf("Enter elements of second array:\n");
 for(i=0;i< n;i++)
 {
  printf("b[%d]=",i);
  scanf("%d", &b[i]);
 }
 /* Merging */
 for(i=0;i< m;i++)
 {
  r[i] = a[i];
 }
 for(i=0;i< m+n;i++)
 {
  r[m+i] = b[i];
 }
 /* Displaying merged array */
 printf("Merged array is:\n");
 for(i=0;i< m+n;i++)
 {
  printf("%d\t",r[i]);
 }

 return 0;
