What will be the output of the code if we give input as sookshmas ?

#includestdio.h
#includectype.h
#includestring.h
int main()
{
    char str[100],a[100];
    int n,i;
    printf("Enter a string\n");
    gets(str);
    n = strlen(str);
    for(i=0;in;i++)
    {
        if(i%2==0)
        {
            a[i] = tolower(str[i]);
        }
        else
        {
            a[i] = toupper(str[i]);
        }
    }
    printf("After string converstion\n");
    for ( i = 0; i  n; i++)
    {
        printf("%c",a[i]);
    }
    return 0;
}
