舉例如下
#import <Foundation/Foundation.h> int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; NSLog(@"%11s%4d", "char", sizeof(char)); NSLog(@"%11s%4d", "short", sizeof(short)); NSLog(@"%11s%4d", "int", sizeof(int)); NSLog(@"%11s%4d", "long", sizeof(long)); NSLog(@"%11s%4d", "long long", sizeof(long long)); NSLog(@"%11s%4d", "float", sizeof(float)); NSLog(@"%11s%4d", "double", sizeof(double)); NSLog(@"%11s%4d", "long double", sizeof(long double)); [pool drain]; return 0; } /* 《程式語言教學誌》的範例程式 http://pydoing.blogspot.com/ 檔名:sizeof.m 功能:Objective-c 程式範例 作者:張凱慶 時間:西元 2013 年 4 月 */
