C++ Programs

Programs in C and C++ languages to develop programming skills and prepare for exams and interviews.

Last Reviewed and Updated on May 20, 2017

This is my own collection of programs in C and C++ programming languages. I have provided solutions to all of them. Write to me if you have a more optimal solution, or you find any mistakes in the solutions. I have myself tested all these programs on Microsoft Visual C++ compiler.

My C/C++ Videos on Youtube

Here is the complete playlist for video lectures and tutorials for the absolute beginners. The language has been kept simple so that anybody can easily understand them. I have avoided complex jargon in these videos.

Convert char from lowercase to uppercase

This program is about converting a lowercase English character to its corresponding uppercase character. It is a simple hack but the C built-in function toupper is definitely faster than this one.

C Program to classify character input

This program asks the user to enter a single character of text. Then it examines the ASCII code to determine whether it is a lowercase, uppercase or a digit. It also shows how a loop can be implemented with statement labels.

Simple C Program to exhibit fuzzy behavior

Don't expect a lot from this program. It simply returns the results of a calculation by using a different formula each time. The end-user doesn't know the internal mechanism, so, to him it appears like a random behavior.

C Program classroom exercise on decisions and loop

This program is here mainly because it demonstrates how a switch statement with its fall through can be easily used to implement a seemingly complicated algorithm.

C Program to demonstrate looping without loops

This program demonstrates how to write a loop without any of the loop constructs. Of course, many programmers would call it a bad programming practice. Nevertheless, it is a nice program that can help us develop skills by writing a program differently.

C Program to write a number guessing game

Here is a program that can guess the number in the mind of a user, of course by asking questions that have either a yes or no as the answer. This program has been written in simple steps that are easy to understand. A well written program is the one which does its job in the least number of steps. Write to me if you have a shorter version.

Program to display a pesudo random message

This program is about one of the most common uses of the modulus operator. This operator can be used to cycle through various case labels of a switch. For example, modulus of any number with 5 will give one of these five digits only 0, 1, 2, 3 or 4,

C/C++ Practice Problem - 1

This is my series on C/C++ problems for accepting user input in a robust way. The questions of this series start from C programs, and they slowly build and convert to classes, and which further build into inheritance. This is Problem 1 of this series.

C/C++ Practice Problem - 2

This is my series on C/C++ problems for accepting user input in a robust way. The questions of this series start from C programs, and they slowly build and convert to classes, and which further build into inheritance. This is Problem 2 of this series.

C/C++ Practice Problem - 3

This is my series on C/C++ problems for accepting user input in a robust way. The questions of this series start from C programs, and they slowly build and convert to classes, and which further build into inheritance. This is Problem 3 of this series.

C/C++ Practice Problem - 4

This is my series on C/C++ problems for accepting user input in a robust way. The questions of this series start from C programs, and they slowly build and convert to classes, and which further build into inheritance. This is Problem 4 of this series.
