Thread: scanf acting weird

Code:

#include<stdio.h>main()
{
 int a,b,g,ind;
char c;
 a=0;


 g=0;
 ind=0;
   for(g=0;g<5;g++)
     {
      printf("insert c\n");
      scanf("%c", &c);


       if ( c=='1' ) {


          a=a*10+  (int) (c-'0');
          ind=1;
                    } 


       if (ind==1 && c!='1' )
                 {


         printf("%d\n" ,a); 
         ind=0;
        a=0;}
 
      }
}

so thats my code and this is what i get from gdb

Code:

(gdb) break 1
Breakpoint 1 at 0x40065e: file kol1.c, line 1.
(gdb) run
Starting program: /home/djordje/Desktop/programiranje/kol1 


Breakpoint 1, main () at kol1.c:3
3       {
(gdb) display c
1: c = 0 '\000'
(gdb) next
6        a=0;
1: c = 0 '\000'
(gdb) next
8        g=0;
1: c = 0 '\000'
(gdb) next
9        ind=0;
1: c = 0 '\000'
(gdb) next
10         for(g=0;g<5;g++)
1: c = 0 '\000'
(gdb) next
12            printf("insert c\n");
1: c = 0 '\000'
(gdb) next
insert c
13            scanf("%c", &c);
1: c = 0 '\000'
(gdb) next
1
15             if ( c=='1' ) {
1: c = 49 '1'
(gdb) next
17                a=a*10+  (int) (c-'0');
1: c = 49 '1'
(gdb) next
18                ind=1;
1: c = 49 '1'
(gdb) next
21             if (ind==1 && c!='1' )
1: c = 49 '1'
(gdb) next
10         for(g=0;g<5;g++)
1: c = 49 '1'
(gdb) next
12            printf("insert c\n");
1: c = 49 '1'
(gdb) next
insert c
13            scanf("%c", &c);
1: c = 49 '1'
(gdb) next
15             if ( c=='1' ) {
1: c = 10 '\n'

commands i used in gdb are bold, the output is standard and the red lines are where the strange thing happens so as you see after the scanf gdb doesnt let me insert my own value for c instead it assigns the default( or is it default) value to c, any help is apriciated thanks

i see, it works when i enter all of my input when i first read c, but is there a way to read the value of c every time the loop repeats itself?
