C++ Source Codes (Beginners)

This is a telephone book simulation program that uses a DOS based menu system. A linked list has been implemented. You will have to save the provided text file on a floppy in order to use the program. Or, you could modify the code accordingly.
The author has asked for comments on how to improve the menu system, so if you have any opinions please do not hesitate to contact him using the email address provided with his name. Thank you.

A typical kiddie puzzle game involving scores. The aim of the game is to arrange all squares in order or to make a picture out of them. Once you finish a puzzle you get 100 points. Every move you make costs you 10 points. Once you go zero the game is over. So the less moves you make, the more you score.

This program demonstrates a function IsSub(char*, char*) that determines whether the string pointed to by the second argument is a sub-string of the string pointed to by the first argument. If it is then the function returns the position of the second string in the first else it will return the value -1.

This program accepts a string and outputs it with only the first occurence of each character. So, for example, if you enter the sentence: "the cat was black", the program will give the output: "the ca ws blk".

This is another mathematical program which calculates any of the variables invovled in the calculations of the equation of a straight line in the order ax² + 2hxy + by² + 2gx + 2fy + c = 0. All conventions are explained within the program itself.

This mathematical program calculates the various variables invovled in the calculations of the equation of a straight line in the order ax² + 2hxy + by² = 0. All the conventions employed by the program are explained within the program itself.

This is a simple C program which basically compares two strings and reports whether they are the same or not.

This program uses looping to convert the input seconds into hours, minutes and remaining seconds.

This is a header file which performs various mathematical operations. You will have to copy it to the \Include directory of your compiler to be able to use it. The exact functions as well as their use have been explained within the header file itself.

This Program takes the coefficients (a,b,c) of a quadratic equation ax²+bx+c as inputs and outputs the resultant roots.

This program uses functions to find the first 10 prime numbers. You can change the number of prime numbers to find by simply changing the while statement.

This is a program which underlines one use of pointers and gives you a sort of idea on how header files work. Here pointers are used to swap 2 predefined numbers.

The random.zip file shows you how to generate random numbers and store them in an array. Furthermore, it shows you how to sort the array in ascending order using functions.

The strings.zip file is a very simple file underlining the use of strings in C++ and information on how to manipulate them. It is a good download for those unfamiliar with the use of strings.
