was wondering how I would be able to store a user inputted string in the format "string,character,integer,integer" into a struct. For example storing "apple,c,5,10" into
typedef struct {
char item[80];
char letter;
int x,y;
}information;
information apple;
I am trying to avoid going through using scanf and a long piece of code to make the comma into a delimiter so wondering if there was any other way to quickly read from scanf and chucking this information into the struct
You can specify complex formats using scanf, like:
scanf("%79[^,],%c,%d,%d", apple.item, &apple.letter, &apple.x, &apple.y);
%79[^,] means scan anything that is not a comma character, up to 79 characters.
Note that this does no error handling if the user enters a poorly formatted string, like "aaa;b;1;2". For that, you'll need to write a lot more code. See strtok
You can use multiple format specifiers in the format string to scanf() to scan all the input at once, through a comma-seperated user input, like
int ret = -1;
if ((ret = scanf("%79[^,],%c,%d,%d", apple.item, &apple.letter, &apple.x, &apple.y)) != 4)
//always check the return value of scanf()
{
printf("scanf() failed\n");
//do something to avoid usage of the member variables of "apple"
}
However, I'll recommend the long way, like
fgets()strtok() and , as delimiterstrtol(), as required).Much safe and robust.
Try to read using the func read() then just split the string using strtok()
