char str[80];
int cnt[122];
int i;

clrscr();

gets( str );
int wrong = 0;
for(i=0; str[i] != '\0'; ++i)

return 1;

getch();

1. when i run the program it says "Expression syntax error on function main." in the expression int wrong = 0;

2. and when i enter a numerical character. it doesn't say Wrong input, although we put Wrong input in else, but instead it closes the program and turns back to the blue IDE. It should say wrong input and will require a user to enter another word.

3. and when i enter a compound word like mother-in-law , it will display the character '-' and will show how many times it appear.
Though it should not be, only the alphabet would be display e.g. (mother-in-law = a,e,h,i,l,m,n,r,t,w) the dash must not be displayed.

1. when you run it or attempt to compile it?

[renren00]

yes when i try to run it

1. I can't duplicate the error. What compiler are you using, I used GCC 4.6.1.

2. I entered "12345" and got "Wrong Input." for output

3. I entered "mother-in-law" and got "Wrong Input." for output.

we are using the old turbo c from the school which i believe is the old one. mother-in-law should be allowed because dash is the only special character to be allowed but it must not display in the analysis part in which the program will count it too.

Is there a reason you're using Turbo C? That will cause all kinds of problems if you're trying to learn modern C.
