Newbie mind wrecking glitch
Hi guys, im working on my school assignment and there is that glitch in my program. it basically skips or ignores my code to read a char. I cant fig it out. my code is as it should be. Please dont ask me why there are so many functions its not my fault its the teachers requirement. we are not supposed to use parameters and use anything except void so... please just help me with those lines to read a character
Code:
none of those 2 work... the compiled proggie just skips the line. using bloodshed 4 (and im not allowed to use anything else.
scanf("%c",&ch);
ch = getchar();
Code:
