Thread: reading characters

Hi,

I am having some problems with my code. I am trying to read characters from scanf. What happens is that it doesnot read the whole character it read only 1 character. I tried making a loop but it keeps giving me errors.

Code:

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

int main()
{
	char c;
	float i;
	int number;
	float f =50;


	scanf("%c", &c);

	number = atoi(c);

	i=f+(float)number;

	printf("%f",i  );

	return 0;
}

atoi takes a string, not a single character, and scanf with %c only reads a single character

You need something like

Code:

char c[10];
fgets( c, sizeof c, stdin );
number = atoi(c);

the thing is that we are only allowed to use scanf and we have to use characters.

It's easier to scanf an int to begin with:

Code:

#include <stdio.h>

int main(void)
{
    int number;

    printf("Please give an integer and press enter: ");

    /* read a number from the keyboard and assign it to 'number' */
    scanf("%d", &number);

    printf("You gave %d\n", number);
}

I am able to do it with strings. but the problem is that the teacher wants us to read character and then we have to convert all those character to floats so I can do some computations.

thanks guys I used fgets since the way my prof is saying it doesnot make sense.Thanks alot.
