Types of Loop
Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.
Loops
Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.
While Loop
Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.
#include<stdio.h>
main(int argc, char *argv[])
{
int n=0;
if(argc==1)
{
printf("No world to examine. \n"); exit(0);
}
/* Loop to count characters */
while(argv[1][++n] != '\0')
{
}
/*Print result */
printf("The world %s has %d characters .\n",argv[1],n);
}

2.What is the purpose of this code:
if(argc==1)
{
printf("No world to examine. \n");
exit(0);
}
