ReadC program to copy one string to another
In this C programming tutorial , we will learn how to copy a string using a built-in library function. The library function we are going to use is char *strcpy(char *dest, const char *src) . We will pass two variables to this function - dest and src. All the contents of src will be copied to dest. Let's take a look into the program first :.

In this tutorial, we will learn how to print a pyramid using star '*' or any other character using 'C programming language'. The user will input the height of the pyramid and we will print the pyramid equal to that height . It will look like as below :.
ReadJava program to replace string in a file
In this tutorial, we will learn how to read strings from a file, how to modify the contents and then again write them back in the same file. We are not taking any inputs from the user. In this example, after reading the contents of the file, we are replacing all 'new' words with 'old'. For example, if the file contain one string This is a new ball., after modification it will become This is a old ball. Let's take a look into the program before moving into more details :.
ReadWrite a C program to calculate profit or loss
In this tutorial, we will learn how to find the profit or loss . We will get the cost price and selling price from the user and store it in different variables. And next, we will check if the user had made a profit or loss by finding the difference between cost price and selling price - selling price - cost price. If the value is more than 0, means selling price is more than cost price , so the user has made a profit. Else, loss. We will also print out the value of the loss or profit.
