Question

I have to read some text from console and then search for the text “simple” in that string. I have:

char Buffer[200];
cin >> Buffer; //read text form keybord

char str[] = Buffer;
char * pch;
pch = strstr (str,"simple");
strncpy (pch,"sample",6);
puts (str);

How to convert Buffer[200] to str[] so that the program works.

Answer 1

If you insist on using C-style strings, you’d probably want something like:

char Buffer[200];
cin >> Buffer; //read text form keybord

char *pos = strstr(buffer, "simple");
if (pos) {
    buffer[1] = 'a';
    puts(buffer);
}

If you want to write actual C++, you’d probably do something more like:

std::string buffer;

std::getline(std::cin, buffer);

int pos;

if ((pos=buffer.find("simple")) !=std::string::npos)
    buffer[pos+1] = 'a';

std::cout << buffer;
