Input in the same line in C

Question

This ( https://code.sololearn.com/cg41nmxdEzQP/#c ) is my simple input program.

I tried something like a "form", where the output syntax looks like:
------------------------------------
<message> : <user-input>
<another-message> : <result>
------------------------------------

But, my code isn't working. What is the reason behind it? And, how can I get my desired "form" output?

Answer 1

1. Add library #include<stdlib.h> at the beginning

2. Allocate memory for your string name.
char* name = malloc(256);

3. If you want free memory using free(name);
