举一反三
- 请写出以下程序的运行结果#include int main() { printf(Hello World! ); return 0; }
- 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; }
- 以下是一个简单、正确的C语言程序 #include int main() { printf('Hello! '); return 0; }
- 以下是一个简单、正确的C语言程序 #include int main() { printf("Hello! "); return 0; }
- 执行以下程序后,输出结果第一行为,第二行为。#include<;stdio.h>;int n=0;void f();int main(){int n;n=2;f();printf("%d\n",n);return 0;}void f(){n=n+5;printf("%d\n",n);}

执行以下程序后,输出结果为。#include<;stdio.h>;int n;void f();int main(){n=0;f();n=n+2;printf("%d\n",n);return 0;}void f(){n=n+5;}

#include [stdio.h] int main() { int a=1; int *pa; pa=&a; printf("a=%d\n",a); printf("*pa=%d\n",*pa); *pa=2; printf("a=%d\n",a); return 0; }的运行结果()

下面程序的输出结果是: #include int main() { int a=3; printf("a=%d,",a); a=a+1; printf("a=%d,",a); a*=2; printf("a=%d\n",a); return 1; }

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; }

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 ;}
