The toupper function C programming converts a lowercase letter to a corresponding uppercase letter. In the default “C” locale, a lowercase letter is any of:a b c d e f g h i j k l m n o p q r s t u v w x y z. which translates respectively to:A B C D E F G H I...
The isalpha function in C programming checks whether the argument passed is an alphabetic character (a to z and A-Z) or not.
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 ...
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 ...
Use thegetnameinfoFunction to IP Address to Host Name in C Thegetnameinfofunction is used in conjunction withgetaddrinfoin this case, and it retrieves the hostnames for corresponding IP addresses. Notice that we process the user input from the first command-line argument and pass it as theget...
Let’s now look at some examples, to understand this function better. We’ll also be usingfork()along withexecvp(), so that we can still have our C program with us! Using execvp() in C / C++ - Some Examples If you want to see what exactly happens if you try to useexecvp()withou...
In addition to the gettimeofday function, another powerful tool for measuring elapsed time in C programming is the clock_gettime function. This function provides a higher resolution and more consistent interface for obtaining time information. The clock_gettime function is part of the header in C...
This C++ Sleep tutorial will discuss the Sleep Function in C++ & see how to put a thread to sleep. We will also learn about the other functions viz. usleep.
1) Have MATLAB call your C++ code as a mex routine, and then use the mexCallMATLAB function inside your C++ code to call back to MATLAB for the functions you want. This is the easiest way to call MATLAB functions and get the results back into your C++ code. Your C++ cod...
Example # 03: Using the printf() Function to Print an Integer and Float Variable in the C Programming Language Now let us see how to use printf() and different format specifiers for additional arguments of different data types in a single printf() and scanf() functions. 2 variables are de...
