IF ELES LOOP

  Conditional statements in c programming :

 (if ,if-else,nested if)
What is a Conditional Statement in C?
Conditional Statements in C programming are used to make decisions based on the conditions. Conditional statements execute sequentially when there is no condition around the statements. If you put some condition for a block of statements, the execution flow may change based on the result evaluated by the condition. This process is called decision making in 'C.'
In 'C' programming conditional statements are possible with the help of the following two constructs:
1. If statement
2. If-else statement
It is also called as branching as a program decides which statement to execute based on the result of the evaluated condition. 
         
             ■IF PROGRAMME LIST■


We use if statement to check a condition and if the condition is true, we run a if- block statement else we process another block of statements that is else-block statements. The else clause is optional. In the case if in the place of condition always zero and non-zero value is checked in which zero means condition false and non-zero means condition true.


 So,here is a list of programmes to help you to understand how if loop work.

FILE HANDLING

By
10.1.1 File Pointers It is not enough to just display the data on the screen. We need to save it because memory is volatile and its contents would be lost once program terminated, so if we need some data again there are two ways one is retype via keyboard to assign it to particular variable, and other is regenerate it via programmatically both options are tedious. At such time it becomes necessary to store the data in a manner that can be later retrieved and displayed either in part or in whole. This medium is usually a ''file'' on the disk. Introduction to file Until now we have been using the functions such as scanf,printf, getch, putch etc to read and write data on the variable and arrays for storing data inside the programs. But this approach poses the following programs. 1. The data is lost when program terminated or variable goes out of scope. 2. Difficulty to use large volume of data. We can overcome these problems by storing data on secondary devices such as Har...
