Hey everyone, I've just started programming and decided to start with C. I have written this program but it will not run and I was wondering if anyone could help me? Your help would be greatly appreciated.
1. #include (stdio.h)
2. void Main (void) {
3. char c;
4. printf("Enter a sentence:\n");
5. scanf("%c", &c);
6. while (c != ".") {
7. printf("%c\n", c);
8. scanf("%c", &c);
9. }
10. printf(".\n");
11. }
First of all, you should use [code] tags around your code.
1. Main should be main (make the 'm' lower case).
2. main() returns int, not void.
3. Should be <stdio.h>, not (stdio.h)
4. To compare against a character, use single quotes -- not double (See the period in your while loop).
Thank you so much,you've helped so much!
And of course, if you are actually compiling with those line numbers in the code, remove them.
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
And since you're a beginner, allow me to add some more information you might like to know, corresponding to bithub's numbers:
1) C is case sensitive, so you can have add, ADD, and Add as all different functions. Your program could have all 3, it just wouldn't be very readable.
2) The C standard says that main returns an int. Return 0 if everything is fine, return other numbers as you please to indicate errors. By default, main will return 0 for you (I think...). The OS uses this - some people don't do it and say "void main works for me" but it's against the standard. (Although I believe some microcontrollers require no return value).
3) Standard header files go in < >'s. When you make your own header files they go in " ";s
4) A single character is single quotes. Using double quotes makes the compiler think it's a whole string, and will return a pointer to the beginning of that string.
Also - when you post problems, also post the specific error message and/or problem.
