c++中exit符号找不到

question:

No clue, it seems very wrong that exit would not work, but what do I know? I'm new to this. Here's the whole file. It's just a sample that I found and am trying to get working for practice. #include <stdio.h> #include <sqlite3.h> static int callback(void *NotUsed, int argc, char **argv, char **azColName){ int i; for(i=0; i<argc; i++){ printf("%s = %s\n", azColName[i], argv[i] ? argv[i] : "NULL"); } printf("\n"); return 0; } int main(int argc, char **argv){ sqlite3 *db; char *zErrMsg = 0; int rc; if( argc!=3 ){ fprintf(stderr, "Usage: %s DATABASE SQL-STATEMENT\n", argv[0]); exit(1); } rc = sqlite3_open(argv[1], &db); if( rc ){ fprintf(stderr, "Can't open database: %s\n", sqlite3_errmsg(db)); sqlite3_close(db); exit(1); } rc = sqlite3_exec(db, argv[2], callback, 0, &zErrMsg); if( rc!=SQLITE_OK ){ fprintf(stderr, "SQL error: %s\n", zErrMsg); sqlite3_free(zErrMsg); } sqlite3_close(db); return 0; } 


answer:

That is because exit is in the

stdlib.h
header if you are coding in C, or
cstdlib
and is then named std ::exit if you are using C++.
