In this article, We will discuss the problem to find three elements from different three arrays such that A + B + C = sum. Consider the below example for a better understanding. Let’s assume A, B, and C are 3 arrays of “N” elements each. Now your task is to find a way for […]

In this article, you will learn how to find the length of a string without using a string header file and loops in C. I will explain two ways to solve the problem of finding the string length without <string.h> and loop. But before understanding the solution let’s first understand what string is in C.

The localtime function in C converts the calendar time pointed to by the timer into a broken-down time, expressed as local time. The localtime function is present in the <time.h> header file. Syntax of localtime: The prototype of the localtime () function is below: #include <time.h> struct tm *localtime(const time_t *timer); Parameters: The

The gmtime function in C converts the calendar time pointed to by the timer into a broken-down time, expressed as UTC. That means it uses the value of the time_t object to fill a tm structure with the values that represent the corresponding time, expressed in Coordinated Universal Time (UTC) or GMT timezone. Syntax of

The difftime() is a C Library function. It computes the difference between two calendar times (time1 – time0 ) in seconds. The difftime function is present in the <time.h> header file. Syntax of difftime: The prototype of the difftime function is below: double difftime(time_t time1, time_t time0); Parameters: The difftime function takes two
