C outputs strings in the order specified by the inputs

#include

main()

int x,y,z;

char str[3][7]=;

printf("The output order is:");

scanf("%d %d %d",&x,&y,&z);

printf("%s %s %s",str[x],str[y],str[z]);

Multiple variables can be added to the input and output, and strings can also be added to the n of str[n]. Hope!!!

Summary. The most commonly used method is the use of pointers, the specific steps are as follows:1

declare a character pointer variable p and initialize it as the first address of the string; 2.Make the pointer variable q point to the end of the string, i.e., q=p+strlen(p)-1;3.Swaps the characters pointed to by pointers p and q, and moves pointer p backward by one position and pointer q forward by one position; 4.

Repeat step 3 until p and q point to the same character, completing the reverse order of the string.

C outputs a string of characters in reverse order.

Make the pointer variable q point to the end of the string, i.e., q=p+strlen(p)-1;3.Swaps the characters pointed to by pointers p and q, and moves pointer p backward by one position and pointer q forward by one position; 4.Repeat step 3 until p and q point to the same character, completing the reverse order of the string.

Pro, include include int main() Here is the complete program: include void main( ).

The general reverse order uses two while, but not many people use it, giving you three common methods.

One sets two pointers to point to the head and tail of the string, then swaps the character that the two pointers point to, and moves the pointer to the middle until it crosses.

char *reverse(char *s) return s ;2. In the recursive way, you need to give a reversed interval and call the method: reverse(s, 0, strlen(s)).

The string s is reversed between the interval left and right, and the recursive method char *reverse( char *s, int left, int right ) three non-recursive methods, which also specify the reverse order interval, is not fundamentally different from method 1, one uses a pointer, and the other uses a subscript.

Reverse the order of the string str between the interval left and right char *reverse( char *s, int left, int right ) return s; }

Function name: strrev

Function: String reversal.

Usage: char *strrev(char *str);

Example: include

#include

int main(void)
