I compile the program with no errors, but when running it give me "segmentation error", help me please.

1. A segmentation error is caused when the kernel detects an attempt to access memory they program is not allowed to access, and sends a segfault signal, which normally kills the offending process.

   Use a debugger (or print statements) to trace where the program is attempting this illegal access, and work from there.

   Note, in C, these are usually cause by a pointer problem or stack overflow.

2. If you intend learning C you will eventually become immune to all the segmentation faults you will get! Segmentation faults are most of the time caused by incorrect pointer referencing such as below:

   { int* a;
   *a= 3;
   }

   If you are new to C and want I would suggest you read this guide http://beej.us/guide/bgc/
   It is very very helpful
