在 c 打印另一个程序

Question

In the original code I have a line:

input = scanf("%c%c%c%c%c", &input_key[0], &input_key[1], &input_key[2], &input_key[3], &input_key[4]);

since I have to print the program out I did:

printf("   input = scanf(\"%c%c%c%c%c\", &input_key[0], &input_key[1], &input_key[2], &input_key[3], &input_key[4]);\n");

however the output came out to:

input = scanf("dd≡Ç", &input_key[0], &input_key[1], &input_key[2], &input_key[3], &input_key[4]);

How to fix this?

Answer 1

% is a special character in printf that is replaced by an input argument. If you want to print the % literal, you should escape it through %% .

So your code should be:

printf("   input = scanf(\"%%c%%c%%c%%c%%c\", &input_key[0], &input_key[1], &input_key[2], &input_key[3], &input_key[4]);\n");
