But why the version without malloc prints an extra char?
They both appear to work... I thought there was an issue. :/

yeah but the version without malloc prints an extra unwanted char

Also Idk why u suggest sizeof(strlen(str)+1) when sizeof(strlen(str)) works just fine
Anonymous
The standard says malloc() has to research non-overlapping memory and that [size + 1] never segfaults, on account of memory read... But always always allocate space for the terminating nul '\0', the terminating nul isn't included in strlen().

how do you control library installation paths in cmake?
i have the following:
install(TARGETS ${PROJECT_NAME} LIBRARY DESTINATION release CONFIGURATIONS Release)
meaning to put a release build into the release folder, but cmake just ignores the destination opt.
it always installs into cmake_install_prefix/lib

I don't know why, the loop inside of my calculatePrice() can't be returned. I tried and the output did not read the TotalPrice. :/

Are the strings matching correctly? In pure C case-sensitive string matches go like: if(!strcmp(str, "abc")) ..., strcmp returns zero when both args have the same chars.

Some languages let you compare with an operator (==) and some want you to use a function or method.

The nested if statements are a bit hard to follow... Of course real-world business logic can be convoluted as well.

I think after printf("Enter Mode Purchase: "); it might be reading a newline instead of a letter... Input is inherently tricky!
#include <stdio.h>
#include <string.h>
#include <ctype.h>
char* readln(int sz, char *buf) {
char *str = fgets(buf, sz-1, stdin);
if(!str) return NULL;
while(isspace(*str)) str++;
int len = strlen(str);
if(len == 0) return str;
while(isspace(str[len-1])) { str[len-1] = '\0'; len--; }
return str;
}
int str2buf(char *str, int sz, char *buf) {
return snprintf(buf, sz-1, "%s", str);
}
int str2char(char *str, char *c) {
if(!str) return 0;
else *c = str[0];
return 1;
}
int str2num(char *str, int *num) {
return sscanf(str, "%d", num);

The function declaration args changed, and one version only compiles with C2x. You probably want a function that prints one at a time.
void displayMovie(int index, struct Movie mv) { ... }
and then
displayMovie(1, movie_1);
displayMovie(2, movie_2);
displayMovie(3, movie_3);
