Nov 22, 2011 · You're looking for the function strcmp, or strncmp from string.h. Since strings are just arrays, you need to compare each character, so this function will do that for you: if (strcmp(favoriteDairyProduct, "cheese") == 0) { printf("You like cheese too!"); } else { …

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++?

Feb 26, 2010 · CheckSubstring(std::string firstString, std::string secondString) deep copies both the strings passed to the function, which is expensive, particularly for longer strings that necessitate heap allocations.

Apr 16, 2025 · C language provides various built-in functions that can be used for various operations and manipulations on strings. These string functions make it easier to perform tasks such as string copy, concatenation, comparison, length, etc. The <string.h> header file contains these string functions.

Dec 12, 2024 · It consists of the test condition and a block of code that is executed if and only if the given condition is true. Otherwise, it is skipped from execution. Let’s take a look at an example: Explanation: The first if statement have a condition that checks if n is smaller than 10.

Mar 5, 2023 · string.h is a standard header file in the C language that contains functions for manipulating strings (arrays of characters). <string.h> header file contains some useful string functions that can be directly used in a program by invoking the #include preprocessor directive. Syntax: #include <string.h> Example:

To compare two strings, you can use the strcmp() function. It returns 0 if the two strings are equal, otherwise a value that is not 0: For a complete reference of string functions, go to our C <string.h> Library Reference.

C string Functions. The <string.h> library has many functions that allow you to perform tasks on strings. A list of all string functions can be found in the table below:

First: #include <string.h> You use strcmp from there. if (!strcmp (s, "question")) .... strcmp returns 0 if the strings are equal, that's why 'not' (!). String comparison in C is done by the use of strcmp function, which means you need to include <string.h> header. Reference: http://www.cplusplus.com/reference/cstring/strcmp/

You need to specify the length of the string argument (%s) that you're asking scanf to read. In this case, 1 character. Also, you need to check the value returned by scanf.
