Repeating a message with for loop #1982

Using for loop construct the same code piece can be repeated a fixed number of times.

Sum of natural numbers within a range – for loop #1986

We use a for loop to sum numbers from 1 to 10. This can changed to any other range also.

Sum of natural numbers within a range – while loop #1989

We use a while loop to sum numbers from values filled in begin and end.

Print table of an integer number #1992

Printing the table of an integer number like 5×1=5, 5×2=10, 5×3=15 and so on.

For and while loop comparison #1995

Comparing simple for and while loop with a simple number printing example

Odd number series with double step counter – for loop #1997

Printing odd number series by incrementing counter in double step using for loop

Odd number series with divisibility test – for loop #1999

Printing odd number series by testing divisibility test on each number in the for loop

Multiple initialisation and multiple step instructions in for loop #2003

A demonstration program to show how multiple initialisation and multiple step instructions in for loop can be used

Print till Z with loop count calculation #2034

As user enters a lower case or upper case alphabet the program prints from that alphabet till z.

Print till Z with while loop boundary crossing #2038

As user enters a lower case or upper case alphabet the program prints from that alphabet till z using the faster technique of while loop iteration and checking for outside boundary condition

Factorial program with limit checking and digit series printing #2042

A program that finds the factorial of a program and checks the limit of number when incorrect outputs may occur due to data size.

Continuous sum using do-while exit on 0 input #2061

This program sums the user inputs continuously and if user input 0 it terminates the loop and displays the sum.

Redo of program activity using a do-while loop #2064

Use of do-while loop to redo or re-perform a program activity using a do-while loop. Here we shall redo the activity of printing a number table.

Write a c++ program to collect a positive integer value from the user and print the list of all natural numbers up to that number. Also print the sum of the natural number printed.

Print all divisors and count of divisors #2016

Write a c++ program to ask an integer number from the user and then print all

Write a c++ program to ask an integer number from the user and then print all its divisors in one line, followed by the count of divisors. The output should be as per example given below.

Enter an integer :45
The divisors of 45 are –

Write a c++ program to print ascii codes and given printable characters from

Write a c++ program to print ascii codes and given printable characters from decimal ascii code 32 to 126 (The printable ascii code range). Print each code and character set in a new line.

Secret code with alphabet divisible by five #2047

Instead of sending his secret code a programmer tells his friend that my secr

Instead of sending his secret code a programmer tells his friend that my secret code is a series of characters which are upper and lower alphabet sequence in their ascending order which are divisible by five. Can you help the programmer’s friend to decipher this code.

Square and square root of numbers in a range #2049

Write a c++ program to output the square and square roots of a number in a ra

Write a c++ program to output the square and square roots of a number in a range where range begin variable is initialised in the variable ‘from’ and range end variable is initialised in the variable ‘to’.
