Read one character at a time with scanf

[daisypolly]

Hi,
How can I read 1 character with scanf and then store all the characters in the variable.for example I am trying to do this but it doesnot work;

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

int main()
{
	char c;
	float i;
	int number;
	float f =50;
	char newchar;
while(c!='\n')
   					 {
   				    /* perform task */

   				      scanf("%c",&c);
   				      newchar=c;
   number = atoi(newchar);
					 }   ;


	i=f+(float)number;

	printf("%f",i  );

	return 0;


}

Hi:

The problem with your code is that you are only converting the last character entered. If you are going to use scanf in this manner, I'd convert a string - not just 1 character:

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

int main()
{
    char c;
    float i;
    int number;
    float f =50;
    char newchar;
    char newstr[50];

    scanf("%s",&newstr);

    number = atoi(newstr);
    printf("%d\n", number);
}

If you're reading one char at a time why on earth are you using scanf? man getc and see how much easier your code gets!

Also

while(c!='\n')

You don't initialize c to any value, so when it gets here it might be '\n' already and the loop would never execute.
