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…
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…
In this article, you will learn to find the length of a string using the strlen() and your own created functions. But before learning the code, I want to explain the meaning of the string in the C programming language. The C string is an array of characters that is…
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…
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…
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:…
In this article, you will learn how to write a C program to display a month-by-month calendar for a given year. I have already written a code to display a calendar for the given month and year. This code compiles in Code Blocks with the GCC compiler. The following…
In this article, you will learn to write a program to calculate age. That means, if the given two dates are dt1 and dt2, you need to calculate the difference between the two dates in years, months, and days. But make sure that the dt1 is earlier than the dt2. For example,…
In this article, you will learn how to find the number of days between two dates. That means, if the given two dates are dt1 and dt2, you need to find the total number of days between them. For example, Input: dt1 = {10, 2, 2022} dt2 = {8, 1,…
In this article, you learn to find the count of leap years in a given year range. That means if S and E are two given years your task is to find the total number of leap years possible in the range (S, E). I assume you already know what…
