Here you will get simple C program to add two numbers. User will input two numbers, then their sum will be calculated and finally it will be printed on screen. The program is given below. C Program to Add Two Numbers Output Enter first number:4 Enter second number:8 Sum=12
#include<stdio.h> #include<conio.h> void main() { clrscr(); //to clear the screen printf(“nnnnttt***** Welcome to C Programming *****”); getch(); //to stop the screen }

Here is the C++ program to find sum of elements above and below the main diagonal of square matrix. Output Enter size of matrix(max 5):3 Enter the matrix: 1 2 3 4 5 6 3 0 2 Sum of elements above the diagonal:11 Sum of elements below the diagonal:7
Here is the C++ program to insert an element in an array. The array must be in ascending order. For example the array is 1 4 6 7. We have to insert 5. Then the resultant array will be 1 4 5 6 7. The program is given below. C++ Program to Insert an Element …
Here you will learn about stack in C++ using a program example. Stack is an abstract datatype which follows Last In First Out (LIFO) principle. Basically stack has two operations namely push and pop. push: inserting an element at the top of the stack pop: removing an element from the top of the stack Below …
