if statments help (C program)

flying11

hello,
i am a learning the c programing language and currently have a problem.
i am writing a code so that if the string .-- is entered that it will print out the letter H instead.

here is my code so far:

char input;
printf("enter the string");
scanf("%s", &input);
if (input == "..-") {
printf("%s", "H");
}

basically my question is how do i define H to be printed out when ..- is entered?
any help would be great as i am stuck at this point

Creamy Goodness

the char datatype will only hold one character.

you'll need to look into implementing a c-string which is basically an array of char datatypes.

Can you further into what problems you are encountering. One thing I see, is in plain English you say "[...] if the string .-- is entered [...]", but in your source code you say: if (input == "..-")

Is it .-- or ..- (of if is morse code, should it H really be ....)

typo, its ment to be ..- = H
its similar to morse code, but it is my own "made up" version of it with my own series of dots and dashes.

i.e my code is not equal to morse code.

Look into char arrays and using fgets rather than scanf.

And also read up on string comparisons and why == will not work

mairtin.l

#include<stdio.h>

int main()
{
char pstring[21]="";
char *pother ="..-";
printf("Enter a string\n");
scanf("%20s",pstring);
if(!strcmp(pstring,pother))//compare two strings, This returns a 1 if false and 0 if true so ! is used
{
printf("Corrent !!!\n");
}
else
{
printf("Incorrent \n");
}
return 0;
}


Hope this helps
