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(...

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 ...

1: Temporary2: string3: to4: be5: parsed Alternatively, another version of the function is available calledstrtok_r, which is a reentrant variant better suited for multi-threaded programs. Both of these functions modify the string passed as the first argument, and they can’t be on constant...
