Learn how to create a Hello World C program by using a text editor, and then compile it by using the command line compiler.
b)Store the count value at b[i].i.e b contains the count numbers of each element of the array. 4)Print the each element along with their count number as printf(“no of %d is %d \n”,a[i],b[i]) using for loop from i=0 to i<n.Here Print Method 1 2 3 4 5 6 7 8 9 ...
printf(“%d”,num),如果在这句代码前一行加上#ifdef DEBUG,后一行加上#endif,代表如果宏定义了DEBUG,那么这句代码就会编译,否则就不编译,也就是可以选择性编译 #if defined(DEBUG) 代码xxxx #endif ,这个跟上面一样,反过来就是#if !defined(DEBUG) ...
So, the program above would become: char name[512]; printf("What's your name? "); fgets(name, sizeof(name) /* 512 */, stdin /* The standard input */); Solution 2: Essentially, their tasks are distinct from one another.
