C Language Example - Output the code of the current file being executed
Output the code of the current file being executed; __FILE__ is the constant for the currently executing file.
Example
#include <stdio.h>
int main() {
FILE *fp;
char c;
fp = fopen(__FILE__,"r");
do {
c = getc(fp);
putchar(c);
}
while(c != EOF);
fclose(fp);
return 0;
}
The output result is:
#include <stdio.h>
int main() {
FILE *fp;
char c;
fp = fopen(__FILE__,"r");
do {
c = getc(fp);
putchar(c);
}
while(c != EOF);
fclose(fp);
return 0;
}
