Loops
1. For
For loop is used to iterate a set of statements based on a condition. Usually for loop is preferred when number of iterations are known in advance.
Syntax
for(Initialization; Condition; Increment/decrement){
//code
}
Example
#include <stdio.h>
int main()
{
for (int i = 1; i <= 5; i++) {
printf("%d\n",i);
}
}

2. While
While is also used to iterate a set of statements based on a condition. Usually while is preferred when number of iterations is not known in advance.
Syntax
while(condition){
//code
}
Example
#include <stdio.h>
int main()
{
int i=1;
while ( i <= 5) {
printf("%d\n",i);
i++;
}
}

3. Do-while
Do-while is also used to iterate a set of statements based on a condition. It is mostly used when you need to execute the statements atleast once.
Syntax
do{
//code
} while(condition);
Example
#include <stdio.h>
int main()
{
int i=1;
do {
printf("%d\n",i);
i++;
} while (i<=5);
}
