In C, also in C++, the for loop executes zero or more times, until the test expression is false...
for (init-expression; test-expression; loop-expression) statement;
/* init-expression executed once, at beginning */
/* statement executes zero or more times, until test-expression is false, test first */
/* loop-expression evaluated at end of each iteration */
for (<init>; <test>; <iterate>) <statement>
<init> is executed once. <test> is then executed - if it has value true (!= 0), then <statement> is executed. Then <iterate> is executed. Then the sequence repeats from the <test> statement. Each of <init>, <test>, <iterate>, and <statement> can be null, and <statement> can be a compound statement. If <test> is false (==0) the first time, then neither <statement> nor <iterate> is executed.
syntax:
for (
meaning:
while (
}
example:
for (i=0, j=10; i tmp= array[i]; array[i]= array[j]; array[j]= tmp; }
for( initial-expression ; conditional-expression ; loop-expression )
{
statement;
}
All expressions are optional, as is the statement body, but semi-colon separators must be present. Multiple expressions are separated by commas.
The initial-expression is executed before entering the loop for the first time only. The conditional-expression is evaluated before entering the loop every time. The loop-expression is executed at the end of each iteration, immediately before the conditional-expression is re-evaluated.
Loop-expressions that increment or decrement values should always use the prefix operators (++x or --x) unless the previous value is required as part of the loop-expression. This is vital when the values are complex objects, to avoid unnecessary temporary variables from being created.
Infinite loops are created with the following:
for( ;; )
{
statement;
if( conditional_expression )
break; // You must include some conditional expression to break from the loop.
}
The continue keyword can also be used with a conditional-expression to start a new iteration at any point in the loop, skipping any remaining statements within the loop.
i dont no answer
No, why did you think so?
#include<iostream> #include<vector> int main() { std::vector<int> integers (12); for (size_t loop=0; loop<integers.size(); ++loop) cin >> integers[loop]; }
printf ("x")
The nested loop.
Yes, you can use for-loop in a C program compiled by Turbo C.
In C++, a for loop is structured as follows: for( int index = 0; index < 10; ++i ) { //do something }
No, why did you think so?
kk
Example: int main (void) { LOOP: goto LOOP; }
Input a variable.
It is unnecessary to use a for loop to convert meters to centimeters. Just multiply by 0.01.
#include<iostream> #include<vector> int main() { std::vector<int> integers (12); for (size_t loop=0; loop<integers.size(); ++loop) cin >> integers[loop]; }
how do we use loops in c plus plus programing and what are basic differences between do,for and while loop
printf ("x")
Add the missing parts.
An infinite loop is one sequence of commands that just repeats over and over again forever. When it comes to creating an infinite loop you can use the: for do while and do statements. using the keywords 'true'
Iterative loops in C/C++ are represented by for(), while() and do...while() code blocks. Recursive loops are represented by functions calling themselves.
