LOOP
LOOP ARE USED TO EXECUTE A BLOCK OF CODE REPEATEDLY UNTIL A CRETAIN CONDITION IS MET .
REAL LIFE EXAMPLE OF LOOP
TYPES OF LOOP :
1) FOR LOOP .
2)WHILE LOOP.
3)DO...WHILE LOOP.
1) FOR LOOP:
.USED WHEN THE NUMBER OF ITERATIONS IS KNOWN.
.CONTAINS ALL LOOP CONTROL IN ONE LINE :
INITALIZATION ,CONDITION AND UPDATION.
SYNTAX: for(int i=0;i<5;i++){
printf("%d",i)}
EXAMPLE:
#include<stdio.h> // header file
int main () {//main fun.
for (int i = 0; i < 5; i++)
{
printf("hello ! i am jiyaa %d\n",i);
}
return 0;//return int value.
}
2)WHILE LOOP :
.USED WHEN THE NUMBER OF ITERATION IS NOT KNOWN IN ADVANCE.
.THE CONDITION IS CHECKED BEFORE THE LOOP BODY EXECUTES.
SYNTAX: int i=0;
while(i<5){
printf("%d",i);
i++;}
EXAMPLE:
#include<stdio.h> // header file
int main () {//main fun.
int i=0; //initialize ist
while (i<5) //give condn
{
printf("hello\n");
i++;//increment
}
return 0;//return int value.
}
3)DO....WHILE LOOP:
.SIMILAR TO THE WHILE LOOP ,BUT THE LOOP BODY EXECUTES AT LEAST ONCE.
.CONDITION IS CHECKED AFTER THE LOOP BODY.
SYNTAX: int i=0;
do{
printf("%d",i);
i++;}
while(i<5);
EXAMPLE:
#include <stdio.h>
int main () {
int i=1;
do{
printf("count :%d\n",i);
i++;
}
while (i<=5);
return 0;
}
