Scanf cycle until carriage returns

Question

I am trying to read user input with multiple fields. But the number of fields is not specified. I want to read all the words until the carriage returns. I tried this code but it does not work:

char str[256]; while(1) { scanf("%s", str); if(str[strlen(str)] == '\n') break; else printf("Got %s\n", str); } 

User input examples:
1. save file1
I need to parse the repository and file1 and exit the loop.
2. Save file1 file2
I need to parse store, file1 and file2 and exit the loop.

It's amazing how to get out of the loop when the carriage returns.

thanks.

Answer 1

Using

 char str[256] scanf("%255[^\n]", str); /*edit*/ 

which will be read in a new line or (Edit :) 255 characters, whichever comes first.

Answer 2

You can read with fgets () and then split the buffer using strtok () into tokens

that way you have complete control over everything.

Answer 3

Currently, the char str [256] array is not populated with anything or unwanted, so when you look, you won't find it.

Answer 4

Try it.

 char str[256]; while(1) { scanf("%s", str); printf("Got %s\n",str); if(fgetc(stdin) == '\n') break; } 

Answer 5

 char str[256] scanf("%256[^\n]", str); 

Be careful with this code. It will overflow the char array for long strings. You want% 255 in scanf to host the null terminator.
