C language to realize string reverse order arrangement

Reverse string order

c Language implementation string reverse order arrangement

Code example

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
 

void nixu(char *dst, char *src, int len)
{
    
    char *dest = NULL;
	char *s = NULL;
    char *d = NULL;

    d = dst;
	s=src+sizeof(char)*len-sizeof(char);
	while(len--!= 0)
	{
    
		*d++=*s--;
	}

	*d=0;
}


int main(void)
{
    	
    char dts[20] = {
    0};
    char src[] = "123456789";
    nixu(dts, src, strlen(src));
    printf(dts);

	return 0;
}
