Read string, float and int value

Demo Code

#include <stdio.h>
#include <string.h>      // for strlen() prototype

#define DENSITY 62.4     // human density in lbs per cu ft

int main()//  ww w  .java 2 s. c  om
{
    float weight, volume;
    int size, letters;
    char name[40];        // name is an array of 40 chars
    
    printf("What's your first name?\n");
    scanf("%s", name);
    printf("%s, what's your weight in pounds?\n", name);
    scanf("%f", &weight);
    size = sizeof name;
    letters = strlen(name);
    volume = weight / DENSITY;
    printf("Well, %s, your volume is %2.2f cubic feet.\n", name, volume);
    printf("Also, your first name has %d letters,\n", letters);
    printf("and we have %d bytes to store it.\n", size);
