我已经尝试过 OutputDebugString
函数,但大多数时候我都会收到如下错误:
error C2664: 'OutputDebugStringA' : cannot convert parameter 1 from 'int' to 'LPCSTR'
例子
尝试 1:
//ERROR: sprintf is unsafe. Use sprintf_s instead
int x = 4;
char s[256];
sprintf(s, "There is %d numbers", x);
OutputDebugString((LPCWSTR)s);
尝试 2:
//FAIL: outputs junk (sprintf_s doesn't understand unicode?)
int x = 4;
char s[256];
sprintf_s(s, "There is %d numbers", x);
OutputDebugString((LPCWSTR)s);
尝试 3:
//ERROR: no instance of overloaded function "sprintf_s" matches the argument list
int x = 4;
TCHAR s[256];
sprintf_s(s, "There is %d numbers", x);
OutputDebugString((LPCWSTR)s);
尝试 4:
//ERROR: no instance of overloaded function "sprintf_s" matches the argument list
int x = 4;
TCHAR s[256];
sprintf_s(s, L"There is %d numbers", x);
OutputDebugString((LPCWSTR)s);
尝试 5:
//ERROR: no instance of overloaded function "swprintf" matches the argument list
int x = 4;
TCHAR s[256];
swprintf(s, "There is %d numbers", x);
OutputDebugString(s);
尝试 6:
//ERROR: 'swprintf': function has been changed to confirm with the ISO C standard, adding an extra character count parameter
int x = 4;
TCHAR s[256];
swprintf(s, L"There is %d numbers", x);
OutputDebugString(s);
最佳答案
它只接受字符串作为参数,而不接受整数。尝试类似
sprintf(msgbuf, "My variable is %d\n", integerVariable);
OutputDebugString(msgbuf);
