#include<stdio.h>

void main()

{

char a[10],b[10],c[20],d;

int i=0,j,k;

//first string

printf("enter the 1st string :");

gets(a);

//second string

printf("enter the 2nd string :" );

gets(b);

//storing first string in temporary variable

for(k=0;a[k]!='\0';k++)

c[i++]=a[k];

printf("do you want to enter space between words y/n :");

scanf("%c",&d);

if(d=='y')

{

c[i++] = ' ';

//concatenating second string with first string

for(j=0;b[j]!='\0';j++)

c[i++] = b[j];

}

else

{

for(j=0;b[j]!='\0';j++)

c[i++] = b[j];

}

c[i++] = '\0';

//printing the concatenated string

for(i = 0;c[i]!='\0';i++)

printf("%c",c[i]);
