A ‘for’ loop is a repetition control structure that allows you to efficiently write a loop that needs to *** a specific number of times.
The syntax of a for loop in C++ is:
for (initialization; condition; increment/decrement)
{
statement(*);
}
The working of a ‘for’ loop:
- The initialization step is **** first, and only once in the beginning. It is used to declare and initialize any loop control variables.
2. Next, the condition is evaluated. If it is true, the body of the loop is ****. If it is false, the body of the loop does not *** and flow of control jumps to the next statement just after the for loop.
3. After the body of the ‘for’ loop executes, the flow of control jumps back up to the increment/ decrement statement and updates any loop control variables.
4. Then condition is evaluated again. If it is true, the loop executes and the process repeats itself (body of loop, then increment step, and then again condition). After the condition becomes false, the for loop terminates.
Example:
include
int main ()
{
\ for loop *****
for(int a = 10;a<20;a = a + 1)
}
count<<"value of a:"<>endl;//
}
return 0;
}
When the above code is compiled and ****, it produces the following result:
value of a: 10
value of a: 11
value of a: 12
value of a: 13
value of a: 14
value of a: 15
