举一反三
- Which of the following program is right? A: include <stdio.h> int main(); { /*programming*/ printf("programming!\n"); return 0; } B: include <stdio.h> int main() { /*programming*/ printf("programming!\n"); return 0; } C: include <stdio.h> void main() { /*programming*/ printf("programming!\n") return 0; } D: include <stdio.h> int mian() { /*programming*/ printf("programming!\n"); return 0; }
- 中国大学MOOC: 以下程序输出的结果是（）# include <stdio.h>int main(){ int a = 4; switch(a ) { case 0: printf("this is 0\n"); break; case 1: printf("this is 1\n"); break; case 2: printf("this is 2\n"); break; default: printf("this is default\n"); } return 0;
- 以下程序没有语法问题的是（） A: B: include<;stdio.h>;int main( ){int x , y = 5 ; printf( "%d\n" , x / y ) ; return 0 ;} C: D: include<;stdio.h>;int main( ){int x = 3 ;y = 5 ; printf( "%d\n" , x / y ) ; return 0 ;} E: F: include<;stdio.h>;int main( ){int x = 3 ,y ; printf( "%d\n" , x / y ) ;y = 5; return 0 ;} G: H: include<;stdio.h>;int main( ){int x = 3 , y = 5 ; printf( "%d\n" , x / y ) ; return 0 ;}
- 以下程序中，运行结果是36的有（）。 A: include <stdio.h> B: define M(y) y*y int main() { printf("%d\n",M(6+0)); return 0; } C: include <stdio.h> D: define M(y) (y)*(y) int main() { printf("%d\n",M(6+0)); return 0; } E: include <stdio.h> int M(int y) { return y*y; } int main() { printf("%d\n",M(6+0)); return 0; } F: include <stdio.h> int M(int y) { return (y)*(y); } int main() { printf("%d\n",M(6+0)); return 0; }
- 下面程序运行后的输出结果是____。 #include <stdio.h> int main() { printf("%d ", NULL); return 0; }
