/* Write a C program to count the lines, words and characters in a given text*/
can you explain how the while loop is terminated here
Program
main()
{
char line[81], ctr;
int i,c,
end = 0,
characters = 0,

lines = 0;
printf(“KEY IN THE TEXT.\n”);
printf(“GIVE ONE SPACE AFTER EACH WORD.\n”);
printf(“WHEN COMPLETED, PRESS ‘RETURN’.\n\n”);
while( end == 0)

/* Reading a line of text */
c = 0;
while((ctr=getchar()) != ‘\n’)
line[c++] = ctr;
line[c] ='\0';
/* counting the words in a line */
if(line[0] =='\0')

else
