C Program to Find the Sum of Even and Odd Numbers

Given a list of integers, separate them into two groups — even numbers (divisible by 2) and odd numbers (not divisible by 2) — and report the sum and count of each group. This is a classic array-scanning problem that demonstrates the modulo operator, accumulator variables, and loop-based input. The original post had no code; …

String Concatenation in C – Custom Function and strcat

String concatenation in C joins two strings end-to-end into a single result. The standard library provides strcat() for this, but writing it manually teaches how C strings work: they are null-terminated char arrays, and concatenation means walking to the end of the destination string then copying source characters one by one until the null terminator. …

C Program to Evaluate sin(x) Taylor Series

The sine function can be computed from scratch using its Taylor series expansion: sin(x) = x − x³/3! + x⁵/5! − x⁷/7! + x⁹/9! − … Each term alternates in sign and uses an odd power of x divided by the corresponding factorial. As you add more terms, the partial sum converges toward the true …

C Program to accept two integers for a co-ordinate point and determine its Quadrant.

The Cartesian coordinate plane is divided into four quadrants by the X and Y axes. Given a point (x, y), this program determines which quadrant it lies in — or whether it falls on an axis or at the origin. The logic is a direct translation of the mathematical definitions into C’s if-else chain. Region …

Prime Number Program in C – Check if a Number is Prime

A prime number program in C checks whether a given integer is prime — divisible only by 1 and itself. Numbers like 2, 3, 5, 7, 11, and 13 are prime; 4, 6, 9, and 12 are not. This page covers two approaches: a basic trial division and an optimized version that skips even numbers, …

C Program to check whether a given 5 digit number is palindrome or not

C program to check whether a given 5 digit number is palindrome or not. Palindromic number is a number that remains same, when it is reversed or can be read in the same way in either direction.Example:12321, 23132… Read more about C Programming Language .
