Question

How to add user defined char and float in array so that the compiler can give the out put in a line

Answer 1

Use typedef to create your own types. The below C example should help:

#include <stdio.h>

typedef char myChar;
typedef float myFloat;

void main()
{
    // Scalars
    myChar ch = 'A';
    myFloat pi = 3.14f;
    printf("The first letter of the alphabet is '%c'.\n", ch);
    printf("The rounded value of PI is %.2f.\n", pi);
    // Arrays
    myFloat floats[10] = { 1.1f, 1.2f, 1.3f, 1.4f, 1.5f, 1.6f, 1.7f, 1.8, 1.9, 2.0f };
    myChar myChars[13] = { 'H', 'e', 'l', 'l', 'o', ' ', 'W', 'o', 'r', 'l', 'd', '!', '\0' };
    printf("A float array: ");
    for (int i = 0; i < 10; i++)
    {
        if (i > 0)
            printf(", ");
        printf("%.2f", floats[i]);
    }
    printf("\nA character array: %s\n", myChars);
}
