Check substring exists in a string in C

Question

I'm trying to check whether a string contains a substring in C like:

char *sent = "this is my sample example";
char *word = "sample";
if (/* sentence contains word */) {
    /* .. */
}

What is something to use instead of string::find in C++?

Answer 1

if (strstr(sent, word) != NULL) {
    /* ... */
}

Note that strstr returns a pointer to the start of the word in sent if the word word is found.

Answer 2

Use strstr for this.

http://www.cplusplus.com/reference/clibrary/cstring/strstr/

So, you'd write it like..

char *sent = "this is my sample example";
char *word = "sample";

char *pch = strstr(sent, word);

if(pch)
{
    ...
}
