C 语言代码实现字符串逆序输出 - 详细解析

The given code reads a set of strings from the user and prints them in reverse order.\n\nHere's a breakdown of the code:\n\n1. The code includes the necessary header files: stdio.h for input/output functions and string.h for string manipulation functions.\n\n2. The main() function is defined.\n\n3. An array of strings arr is declared with a size of 80x80.\n\n4. A character a and an integer i are declared.\n\n5. A for loop is used to read strings from the user until the newline character \n is encountered. The loop iterates until a is not equal to \n. \n\n Inside the loop, scanf("%s%c",&arr[i],&a); is used to read a string into arr[i] and a character into a. \n\n Note: %s format specifier is used to read a string, and %c format specifier is used to read a single character.\n\n6. After the loop, i is decremented to point to the last valid index.\n\n7. Another for loop is used to print the strings in reverse order. It starts from i and iterates until i is greater than or equal to 0. i-- is used to decrement i in each iteration.\n\n Inside the loop, printf("%s",arr[i]); is used to print the string at index i. \n\n If i is not equal to 0, printf(" "); is used to print a space after each string except the last one.\n\n8. Finally, the main() function returns 0 to indicate successful execution of the program.\n\nNote: The given code does not handle input errors or check for array bounds. It assumes that the user will input strings within the specified array size.
