C program to read multiple lines of text and then count the number of characters words and lines in the text

#include <stdio.h>
#include <conio.h>
int main()
{
char str[1000];
int i=0, word_count = 1, line_count =1, char_count = 1;
clrscr();
printf("\n Enter a ‘*’ to end");
printf("\n ****");
printf("\n Enter the text : ");
scanf("%c", &str[i]);
while(str[i] != '*')
{
 i++;
scanf("%c", &str[i]);
}
str[i] = '\0';
i=0;
while(str[i] != '\0')
{
if(str[i] == '\n' || i==79)
line_count++;
if(str[i] == ' ' &&str[i+1] != ' ')
word_count++;
char_count++;
 i++;
}
printf("\n The total count of words is : %d", word_count);
printf("\n The total count of lines is : %d", line_count);
printf("\n The total count of characters is : %d", char_count);
return 0;
}
