Scanf() inside while is not working. Without while it works.

#include <stdio.h>
int main ()
{
        int test,i,l=0,j;
        char name[100],name1[100];
        scanf("%d",&test);
        while(test--)
        {
                scanf("%[^\n]s",name);
                l=strlen(name);
                for(i=0;i<=l;i++)
                {
                        if (name[i]>=97 && name[i]<=122)
                        {
                                name1[i]= name[i]-32;
                        }
                        else
                        {
                                name1[i]= name[i];
                        }
                } 
                printf("%s",name1);
        }
        return 0;
}

I don't get the error.

What does "not working" mean? You need to describe exactly what's happening, what you want to happen, and what you've tried. – Carcigenicate Oct 13 '16 at 19:30

Use `toupper()` to convert letters to uppercase, not your own code. – Barmar Oct 13 '16 at 19:35

Thanks @Carcigenicate if i put several blank spaces at the start of a string the blank spaces are omitted while printing. – Trojan Oct 13 '16 at 19:51

Suggest using `fgets()` [C: loop on scanf](http://stackoverflow.com/questions/35281009/c-loop-on-scanf) – chux - Reinstate Monica Oct 13 '16 at 20:54
@Trojan you passed name without & in scanf function scanf("%[^\n]s",name); that is not true make it correct like scanf("%[^\n]s",&name); and try it – lazyCoder Oct 14 '16 at 12:09
