In this example, we will see how to display the integer with the printf() function. We will also use the scanf() function, which is used to read character, string, and numeric data from the input device. An integer variable is declared first with no value assigned to it. Then printf(...
How to Use Recursive Function in C When arecursive functionis called, it sets aside some memory to run its operations. If the condition is met, it passes the result back to the previous function, which also frees up the memory it set aside. This process keeps repeating until the function ...
The assert keyword is used to perform an expression as a function parameter, and it evaluates it during memory allocation. So we can use the malloc() method to write and evaluate expressions on the variable. If the expression evaluation fails or returns the Boolean value as false, the same ...
When we use the Linux or UNIX operating system, we need to include “unistd.h” header file in our program to use thesleep ()function. While using the Windows operating system, we have to include “Windows.h” header to use the sleep () function. So in order to write a cross-platfor...

We can call the STM32 HAL functions (e.g. HAL_UART_Transmit), but sometimes it’s easier to use the standard C library functions printf, scanf, and so on. To do that, we need to re-write the underlying functions.Note: the code for this section is taken from Carmine Noviello’s ...
Once you complete your input with an ENTER, then the string will be returned in tstr. Then you can use scanf() to convert the filtered string into a number if that's what you want to do next. Here's a code fragment using GetString(). #define TSTR_SZ 30 char tstr[TSTR_SZ]...
When is it appropriate to use scanf() as opposed to fgets()? Although bothfgets()andscanf()can read string inputs, it would be better to pick one over the other in some scenarios. For reading from open files, you are required to declare fgets() whereas reading from keyboard opens up ...
