This program accepts a number from the user and finds the sum of all the numbers up to the number entered by the user. SAMPLE PROGRAM: #include <iostream.h> #include <conio.h> int recursion(int num); int main() { int num = 0; int sumnum; cout << "Enter any integer greater than 0: " << endl; cin >> num; sumnum = recursion(num); cout << "The sum is: " << sumnum << endl; cin.ignore(); cin.get(); return 0; } int recursion(int num) { int sum = 0; if(num == 1) return 1; else   {     sum = recursion(num - 1) + num;     return sum;   } } OUTPUT: Enter any integer greater than 0: 6 The sum is: 21 ALSO CHECK THE FOLLOWING C++ PROGRAMS: --  C++ Program To Accept & Print The User’s Age. --  C++ Program To Print A String. --  C++ Program To Accept & Display A Number. --  C++ Program To Print Sum Of Two Values. --  C++ Program To Print S...

This program accepts two numbers from the user and finds out the greatest common divisor of the two numbers. SAMPLE PROGRAM: #include <iostream.h> #include <conio.h> int GCD(int a, int b) { int remainder; while( b != 0 )   {     remainder = a % b;     a = b;     b = remainder;   } return a; } int main() { int x, y; cout << "To find the greatest common divisor, enter the values specified below \n"; cout << "Value 1: "; cin >> x; cout << "Value 2: "; cin >> y; cout << "\nThe Greatest Common Divisor of " << x << " and " << y << " is " << GCD(x, y) << endl; return 0; } OUTPUT: To find the greatest common divisor, enter the values specified below Value 1: 20 Value 2: 10 The Greatest Common Divisor of 20 and 10 is 10 ALSO CHECK THE FOLLOWING C++ PROGRAMS: --  C++ Program To Accept & ...

This program helps to find out the square root of the number entered by the user.
