hi @prashanthth not sure what exactly you mean by a “paragraph” but clearly your code doesn’t seem to be a good one. You don’t need to use a for loop.

Assumption:
I assume that you basically want to input a string which has spaces, and since you do not want to use a gets() you can use an alternative ie getline(). For that you can use this in c++:


int main()
{
    char a[100];
    cin.getline(a,100);
    cout << a;
}
</pre>

If that doesn’t answer your question, i would request you be a little more specific as to what your requirement is, or even post the problem link which you are solving. :slight_smile:

agree with @yo_baby. You just need to include the proper header.

Don’t understand what you are asking but

  1. if you want to use gets() then include stdio.h header.

    #include<stdio.h>
int main(){
 char a[100];
 gets(a);
 return 0;
}

  2. If you don’t want to use gets() then you can use getline.

  • gets()

    If you are using headers of both c and c++ in c++ then you need namespacing.

      #include<stdio.h>
  #include<iostream>
  #include<cstring>
  using namespace std; // add this line
  int main()
  {
   char a[100];
   gets(a);
   puts(a);
   return 0;
  }

  • getline()

     #include<iostream>
 #include<string>
 int main ()
 {
   string name;    
   cout << "Please, enter your full name: ";
   getline(cin,name);
   cout << "Hello, " << name << "!\n";
   return 0;
 }
