Question
C programming: I am getting the following errors in my program. Would someone kindly review my errors and code and assist me in finding how to address it. I cannot use any fancy coding, this is a beginners course and we are limited to loops and maybe strings. Absolutely no pointers. Thank you so much.
Errors:
Code:
Three files; stocks.c, stats.c, and io.c:
stocks.c:
* stocks.c
* program is for input stock price using a for looping construct
*
*
* gcc -o stocks.x stocks.c
* ./stocks.x
