{
 int ch;

 ch = getchar();
 printf("%d", ch);
}

output will be   .. 49   the ASII value of the character 1  


the above i have no problems with,
BUT,,  can someone explain the following..


{
 int ch;

 cscanf("%c", &ch);
 printf("%d", ch);
}

lets say i enter .. 1
output will be   .. 4210737  where does this value come from??

Initialse the int variable to something [say ch = 0 ] and your problem would be solved

Basically when u are using %c, only one byte of the integer variable is getting populated with the data and the other byte contains it's initial junk value

Thus the result u obtained

After initialising it to 0, everything works fine
