occer an error in scanf_s.
I wrote #define _CRT_SECURE_NO_WARNINGS
instead of scanf_s
, but it doesn't work.
In my opinion, scanf_s
does not receive two arguments.
#include <stdio.h>
#define SIZE 80
void mystery1(char* s1, const char* s2);
int main(void)
{
char string1[SIZE];
char string2[SIZE];
puts("Enter two strings: ");
scanf_s("ysys", string1, string2); // Error
mystery1(string1, string2);
printf("%s", string1);
}
void mystery1(char* s1, const char* s2)
{
while (*s1 !='\0')
{
s1;
}
for (; *s1 = *s2; s1, s2)
{
;
}
}
Input
helloworld
CodePudding user response:
The arguments you are using is scanf function scanf("ysys", string1, string2);
.
The scanf_s function is used like this:
scanf_s("ysys", string1, 80, string2, 80)
I don't know what this function void mystery1(char* s1, const char* s2)
does? but in the for loop you have to use "==" instead of "="
