将上述代码复制到一个新的C文件中,例如 sign_function.c。 使用C编译器编译该文件,如使用 gcc: gcc -o sign_function sign_function.c 运行生成的可执行文件: ./sign_function 按提示输入一个整数,程序将输出该整数的符号函数结果。示例输出假设用户输入了 5,则输出将是:请输入一个整数: 5 符号函数的...

sign*=-1; // sign=-1*sign ……} //sign不是c语言的库函数，sign(z,p)； //表示对一个名为sign的函数调用,传递参数是变量z，p。在c语言里面，非零就是真的意思，零就是假的意思，sign=0，就是将0赋值给sign，或者是将sign赋值为假，!sign就是真的意思，顾名思义，sign就是标记的意...

Inside the function, you can add as many parameters as you want:Example void myFunction(char name[], int age) { printf("Hello %s. You are %d years old.\n", name, age);}int main() { myFunction("Liam", 3); myFunction("Jenny", 14); myFunction("Anja", 30); return 0;}// ...
// This function returns a pointer to the // signed and encrypted BLOB and also returns // the length of that BLOB. pbSignedAndEncryptedBlob = SignAndEncrypt( pbToBeSignedAndEncrypted, cbToBeSignedAndEncrypted, &cbSignedAndEncryptedBlob); _tprintf(TEXT("The following is th...
符号位(sign bit): 对于补码表示,MSB(Most Significant Bit)表示整数的符号; 0 for nonnegative; 1 for negative。 无符号数与带符号数 范围 在带符号数中,负数范围个数总比整数范围个数多1,举例: 00000000表示0; 00000001表示1; 01111111表示127;
if( CryptSignMessage( &SignMessagePara, FALSE, 1, rgpbToBeSigned, rgcbToBeSigned, NULL, &pEncodedBlob->cbData)) { printf("The needed length is %d \n", pEncodedBlob->cbData); } else { MyHandleError("Getting the length failed.\n"); } ...
