in my program,i give each user an ID code but maybe user forget ID, then i want to search his or her name in a way that if i print part of the user's name ,program shows me all of names which have that part then i choose between them. how can i do that??
but with strstr we can find the exact name.i want to type part of the name then compiler shows me all of the names with this part then i can choose.
No, you're thinking of strcmp. strstr is a function that finds substrings of a string, so if you give it the parameters "look it up in the docs bozo" and "docs" then it will give you a pointer to "docs", thus confirming that "docs" is indeed in the string.
