Answer 1

for null termination you're using '\O' ( oh ) istead of '\0' ( zero )..

you can also compare it with 0
also line 13 you shouldn't compare char with string
" " is a string ( null terminated ) while ' ' is just space char.. same goes for assignment line 15,16

so a working code would be like :

#include <stdio.h>
#include<string.h>
int main()
{
char str1[10]="anuj ",str2[10]="ansh";
int i ,j,count1=0,count=0;

for(i=0;str1[i]!='\0';i++)
{
for(j=0;str2[j]!='\0';j++)
{
if(str1[i]==str2[j]&&str2[j]!=' ')
{
str1[i]=' ';
str2[j]=' ';
break;
}
count++;

}
count1++;
}
printf("%s",str1);
printf("%s",str2);

}
