I read about trigraphs on MSDN site..and tried the following code..
Giving me error on the first.. line where I am trying to replace the punctuation character with the trigraph.. why is it.. so.. I cant understand.. There is no problem using. trigraph. after the main() header..Code:??=include <stdio.h> // ??= is equal to punctuation character # int main(void) ??< // ??< is equal to punctuation character { printf("Hello World\n"); ??> // ??> is equal to punctuation character }
