How does the for loop work in c?

Answer 1

• For loop is "Counter controlled loop" i.e. a counter or control variable is used to process the for loop , as discussed in earlier chapters.
• For loop is an "Entry controlled loop" i.e. the condition to iterate the loop must be check at the starting of the loop and loop body will not execute if the condition is False. Source website:

Answer 2

for(initialization; condition; end_action) {

code

}

* initialization - used to initialize variables (usually something like i = 0)

* condition - boolean expression; loop continues while expression is met

* end_action - action to perform at the end of the loop (usually something like i++)

* code - code to repeat Note that any of the above sections can be empty:

for(;;){}

This is a valid code block which will do nothing and never finish.

Answer 3

Hi,

Nested loop is loop inside the loop.

example

for(i =0;i<0x12;i++)

{

for(j= 0;j<0x20;j++)

{

// sample of nested loop

}

}

Answer 4

No limit, you may have as many loops (nested or separated) as you need.

You can use any or all of these:

1. while (exp) stmt

2. for (exp; exp; exp) stmt

3. do stmt while (exp);

4. LABEL; stmt ... goto LABEL

5. recursion

Answer 5

For loop, while loop, do while loop and goto loop.

Answer 6

In C: when inside a loop there is another loop

In other languages: when inside a loop there is another loop

Answer 7

This is used to enable the computer to execute a particular piece of code as many times as required without increasing the complexity of the source code, making it easier to read and maintain
