Write a function reverse which takes a string as an argument, reverses the string and returns a new string that is the reverse of the original.
Note: you will need to malloc space for this new string!
For example:
Test
char str[]="hello";
char *rts reverse(str);
printf("%s/%s", str,rts);
Result
Answer: (penalty regime: 0 %)
1 #include <stdio.h>
2 #include <stdlib.h>
3 #include <string.h>

hello/olleh
char* reverse(char str[])
{
char *rts = (char*) malloc(strlen(str)* sizeof(char)); //allocating memory for pointer
7 char *start=rts; //starting address of pointer is stored in start
8 for(int i=strlen(str)-1;i>=0; i--) //traversing the str[] array from last to first
9-{
Check
10 *rts=str[i]; //storing the element of str[i] to rts
11
rts++; //incrementing pointer
12
}
13
return start; //rerturning starting address of the pointer
14
}

int main()
16 {
17 char str[100]="hello";
18 char *rts=reverse(str);
19 printf("%s/%s", str, rts);
20 return 0;
21}
Syntax Error(s)
_tester__.c:31:5: error: redefinition of 'main'
int main() {

tester__.c:23:5: note: previous definition of 'main' was here
