In this article, we learned about using the getch() function in C / C++ to receive character input from the keyboard.Code: Select all Unhandled exception: page fault on read access to 0x00000018 in 64-bit code (0x0000000140c8c104). Notice that I have 6 characters in my output string, since we need to reserve 1 byte for ‘\0’. Indeed, when I typed “Hello”, I did get the output correctly. So on typecasting, the ASCII value 49 will be cast to the char value of ‘0’!Īs a simple example, let’s first look at reading a single character. Now, in C / C++, we can directly convert a character to an integer.
Here, getch() returns the ASCII value of the character read from stdin.įor example, if we give the character ‘0’ as input, it will return the ASCII value of ‘0’, which is 49. This function does not take any parameters. This is there as part of the header file, so you must include it in your program. This function takes in a single character from the standard input ( stdin), and returns an integer. Let’s take a look at using this function, using a few examples. So, we can still use this function from Windows / Linux / Mac. While this is not a part of the C standard, this is still a POSIX C function. The getch() function is very useful if you want to read a character input from the keyboard.
