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

int main()
{
    int i=0;
    char s[1000],temp[1000];
    scanf("%s",s);
    while(s[i+2]!='\0')
    {
        temp[i]=s[i+1];
        i++;
    }
    temp[i]='\0';
    printf("%s\n",temp);
    return 0;
}

Your homework - that means you should do it.

Solving problems yourself is the whole point of it, at least for those who actually wish to learn.

Solution 4

#include <stdio.h>
#include <stdlib.h>
void main()
{
char a[100];
int n,m,i,j;
scanf("%s",a);
n=strlen(a);
m=n;
for(i=0;i<n;i++)
{
if(m>2)
{
for(j=i+1;j<n-1-i;j++)
{
printf("%c",a[j]);
}
printf("\n");
m=m-2;
}
}
}

Almost 6 months and your code does not fit the question !

Tip 1: learn programming by using the debugger and make some console output.

Tip 2: You can use the function strncpy to copy the desired amount of chars.

Tip 3:

C++

char *p = (s + 1);

Solution 2

You need a slightly bigger array (for a 0-terminated string of 1000 characters, you need 1001 of them).
Then you need the length of the string, say len.
Eventually set start = 0 and make a loop while (len >=1) , at each iteration

output len characters, starting from start.
increment start.
decrement twice len

This is your homework, so it's part of your task to get it working properly - this is a process called "debugging" and it's a skill that only gets better with use.

I have no idea what system you are using, but you almost certainly have a debugger available, which will let you run your code and look at what is going on at the same time. Google "debugger" and the name of your IDE and you should find instructions.

But I'll give you a hint: how many times do you look at the original string? Have you considered nested loops?

Remove first and last till end
