A loop in computer languages is a set of statements that execute repeatedly, based on some criteria.
In C and C++, the three looping statements are while, do, and for...
while (test-expression) statement;
/* statement executes zero or more times, until test-expression is false, test first */
do statement while (test-expression);
/* statement executes one or more times, until test-expression is false, test last */
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 */
Often, statement, is a set of statements, such as...
while (test-expression) {
... statements
}
for( ; ; ) { statement_block; } while( conditional_expression ) { statement_block; } do { statement_block; }while( conditional_expression )
C: there are no methods in C. C++: no.
In its simplest form, the expression "c plus c plus c" can be simplified by combining like terms. Since there are three instances of "c," it can be expressed as 3c. Thus, the simplest form is 3c.
A while statement is one type of looping statement. by which we can start a loop in our programs. while loop is precondition checking statement, because it first check its condition then loop will go to its body part. EX. while(i>0) { //body part } here when i will >0 then it will check it body part and execute it and display result.
c is procedure oriented and c++ is object oriented & much newer.
Looping means you repeat a particular procedure a specified number of times or until a defined condition is met.
There are several 'looping' statements in C++. They are:while () { }do { } while () ;for (index-start, index-end; index increment/decrement) { }They are used to repetitively execute statements as long as the statement(s) controlling the loop are true.
for( ; ; ) { statement_block; } while( conditional_expression ) { statement_block; } do { statement_block; }while( conditional_expression )
differance between control statement and looping statement?
for (int x = 0; x < 5; x++){cout
for,while,do while
while, for, do-while (and perhaps goto)
What is looping statement?
b+b+b+c+c+c+c =3b+4c
c + c + 2c + c + c = 6c
b + b + b + c + c + c + c = 3b + 4c
4c
