Hello, I am a beginner in C programming and would like help with this small piece of code. It is supposed to ask you your name and then repeat it back to you:
When executing the program, it just says "Hello, 0" when you type in letters. when you type in numbers it says hello and then the number.Code:#include <stdio.h> #include <stdlib.h> int main() { char (num); printf("Hello, what is your name? "); scanf("%d" ,&num); printf("Hello %d.", num); }
This is not what you want:
You want to store a name, so you need to store a string, not a single char. Furthermore, the parentheses are unnecessary. What you could do is to decide on a maximum length for the name, and then declare an array one more than that length (for the null character), e.g.,Code:char (num);
Then you use %s with a field length to read the name:Code:char name[50];
In the above code snippet, I used 49 since that is the maximum length for the name. I also checked that scanf returned 1, otherwise there must have been some kind of input error.Code:if (scanf("%49s", name) == 1) { /* ... */ }
Oh, and then remember to print using %s, not %d, since you have a string.
