Each input line to the above programs, either from keyboard or from the text file, ends with an invisible new line character. Modify the program countChar so that it counts only visible characters, i.e., new line character is not counted. Name your program countChar3.c.

greetings.txt:

hello

how are you

I am good

countChar.c

#include //define EOF

main() {

int c;

int count = 0;

c = getchar();

while(c != EOF) /* no end of file */

{

count++; //include spaces and ' '

c = getchars(); /* read next */

}

printf("# of chars: %d " ,count);

}

Sample Inputs/Outputs:
