Format match, look not to come out ~ from the code

CodePudding user response:

Match, use a third-party cryptography library

CodePudding user response:

Debug it and see, you see

Parameters: \ np: printf (" % s \ na: % s \ nb: % s \ nn % s \ \ n \ nGy nGx % s % s ", p, a, b, n, Gx, Gy);
Must be a variable and the matching problem of format character
