The general design of the for loop is reflected in some form or another in all procedural programming languages However, in C/C++, it provides unexpected flexibility and power The general form of the for statement is for(initialization; condition; increment) statement; The for loop allows many variants, but there are three main parts: 1 The initialization is usually an assignment statement that sets the loop control variable 2 The condition is a relational expression that determines when the loop exits 3 The increment defines how the loop control variable changes each time the loop is repeated These three major sections must be separated by semicolons The for loop continues to execute as long as the condition is true Once the condition becomes false, program execution resumes on the statement following the for In the following program, a for loop is used to display the numbers 1 through 100 on the screen:

Program Control Statements
int main(void) { int x; for(x=1; x <= 100; x++) printf("%d ", x); return 0; }
THE FOUNDATION OF C++
In the loop, x is initially set to 1 and then compared to 100 Since x is less than 100, printf( ) is called and the loop iterates This causes x to be increased by 1 and again tested to see if it is still less than or equal to 100 This process repeats until x is greater than 100, at which point the loop terminates In this example, x is the loop control variable, which is changed and checked each time the loop repeats Here is an example of a for loop that iterates a block of statements:
for(x=100; x != 65; x -= 5) { z = x*x; printf("The square of %d, %d", x, z); }
Both the squaring of x and the call to printf( ) are executed until x equals 65 Note that the loop is negative running: x was initialized to 100, and 5 is subtracted from it each time the loop repeats An important point about for loops is that the conditional test is always performed at the top of the loop This means that the code inside the loop may not be executed at all if the condition is false to begin with For example:
x = 10; for(y=10; y != x; ++y) printf("%d", y); printf("%d", y); /* this is the only printf() statement that will execute */
This loop never executes because x and y are equal when the loop is entered Because this causes the conditional expression to evaluate to false, neither the body of the loop nor the increment portion of the loop executes Thus, y still has the value 10, and the only output produced by the fragment is the number 10 printed once on the screen
for Loop Variations
The previous discussion described the most common form of the for loop However, several variations of the for are allowed that increase its power, flexibility, and applicability to certain programming situations
Borland C++ Builder: The Complete Reference
One of the most common variations uses the comma operator to allow two or more variables to control the loop (Remember, the comma operator strings together a number of expressions in a do this and this fashion See 2) For example, the variables x and y control the following loop, and both are initialized inside the for statement
for(x=0, y=0; x+y < 10; ++x) { scanf("%d", &y); }
Commas separate the two initialization statements Each time the loop repeats, x is incremented and y s value is set by keyboard input Both x and y must be at the correct value for the loop to terminate Even though y s value is set by keyboard input, y must be initialized to 0 so that its value is defined before the first evaluation of the conditional expression (If y s value is not set, it could, by chance, contain the value 10, making the conditional test false and preventing the loop from executing) Another example of using multiple loop-control variables is found in the reverse( ) function shown here reverse( ) copies the contents of the first string into the second string, in reverse order For example, if "hello" is stored at s, then after the call r will point to "olleh"
/* Copy s into r backwards */ void reverse(char *s, char *r) { int i, j; for(i=strlen(s)-1, j=0; i > =0; j++, i--) r[i] = s[j]; r[j] = '\0'; /* append null terminator */ }
The conditional expression does not have to involve testing the loop control variable against some target value In fact, the condition may be any relational or logical statement This means that you can test for several possible terminating conditions For example, you could use the following function to log a user onto a remote system The user has three tries to enter the password The loop terminates when the three tries are used up, or when the user enters the correct password
void sign_on(void) { char str[20]; int x;
