how can I split a multi-line string in const char* array.?
Here is the input string.
const char* str = "122.123,-38.789"
"122.123,-39.78";
I need to get two string from this.
str1 = "122.123,-38.789";
str2 = "122.123,-39.78";
output of
printf("string='%s'", str)
string='122.123,-38.789122.123,-39.78'
What should be done to split this string ?
Use an array of char *
#include <stdio.h>
const char* str[] = { "122.123,-38.789" , "122.123,-39.78" };
int main(){
printf("%s\n%s\n",str[0],str[1] );
return 0;
}
The C pre-processor concats strings placed together,
const char* str = "122.123,-38.789"
"122.123,-39.78";
The linebreak between the strings is parsed as a blank, treated the same as a space or a tab. So it's equivalent to:
const char* str = "122.123,-38.789" "122.123,-39.78";
which the preprocessor converts to
const char* str = "122.123,-38.789122.123,-39.78";
