Loop Control statements

Loop Control Statements in C Language

Loop control statements allow code to be executed repeatedly based on a condition. They are used to automate repetitive tasks.

🔹 1. for Loop

Used when the number of iterations is known.

for (int i = 1; i <= 5; i++) {
    printf("%d\n", i);
}

🔹 2. while Loop

Used when the number of iterations is not known in advance; the condition is checked before the loop runs.

int i = 1;
while (i <= 5) {
    printf("%d\n", i);
    i++;
}

🔹 3. do-while Loop

The loop runs at least once, because the condition is checked after the body executes.

int i = 1;
do {
    printf("%d\n", i);
    i++;
} while (i <= 5);

🔹 4. break Statement

Used to exit the loop immediately.

for (int i = 1; i <= 10; i++) {
    if (i == 5)
        break;
    printf("%d\n", i);
}

🔹 5. continue Statement

Skips the current iteration and proceeds to the next one.

for (int i = 1; i <= 5; i++) {
    if (i == 3)
        continue;
    printf("%d\n", i);
}

🔹 6. goto Statement

Jumps to a labeled statement (not recommended in modern programming).

int i = 1;
start:
if (i <= 5) {
    printf("%d\n", i);
    i++;
    goto start;
}
