C For Loop
Used to iterate a specific number of times.
Syntax:
for (initialization; condition; update) {
// Code to be executed in each iteration
}
Syntax:
for (initialization; condition; update) {
// Code to be executed in each iteration
}
- Initialization - It initializes the variable for the loop to process.
- Condition - Checks the condition before iteration. If false it exits the loop.
- Update - It increments or decrements the variable used to initilize the loop.
Example
#include <stdio.h>
int main() {
// Print numbers from 1 to 5 using a for loop
for (int i = 1; i <= 5; i++) {
printf("%d ", i);
}
return 0;
}
See how the loop works
- int i = 1 initializes the variable i to 1.
- i <= 5 is the condition that checks if i <= 5.
- i++ increments the value of i after each iteration
Using Arrays
Example
#include <stdio.h>
int main() {
// Iterating through an array
int numbers[] = {10, 20, 30, 40, 50};
for (int i = 0; i < 5; i++) {
printf("%d ", numbers[i]);
}
return 0;
}
