for Loop in C

There may be a situation, when you need to execute a block of code several number of times. In general, statements are executed sequentially: The first statement in a function is executed first, followed by the second, and so on. Programming languages provide various control structures that allow...

Break Statement in Java

Break StatementIn java , the break statement has three uses.1. It terminates a statements sequence in switch statement.2. It can be used to exit a loop.3. It can be used as a "civilized" form of goto. The first use we had seen in swtich statement's post.And last two uses are explained here. 2. Using the break to exit loop:By break  , you can force to terminates the loop.When a break statement...

Break And Continue in C

Break: The break statement allows you to exit a loop from any point within its body, bypassing its normal termination expression. When the break statement is encountered inside a loop, the loop is immediately terminated, and program control resumes at the next statement following the loop. The...

Switch-Case Statement in C

While if is good for choosing between two alternatives, it quickly becomes typical when several alternatives are needed. C's solution to this problem is the switch statement. The switch statement is C's multiple selection statement. It is used to select one of several alternative paths in program execution and works like this: A variable is successively tested against a list of integer or character...

Do-While Loop in C

While loops causes program to execute the certain block of code repeatedly until some conditions are satisfied, i.e., loops are used in performing repetitive work in programming. Suppose you want to execute some code/s 10 times. You can perform it by writing that code/s only one time and repeat...

Java Control Statements

In this post we are going to discuss the control statements. The control statements are used to control the flow of execution of the program. Different type of control statements are: 1. Selection statements. 2. Iteration or looping statements. 3. Jump statements. 1.Selection statements:  Java supports two selection statements if and switch. These  statements allows you to control the...
