# This was how I did my first challenge

Hello,

Just wanted to share with you guys how I completed my first challenge. I don’t know if this is completely correct but I hope it’s along the lines. I’m used to C++ so I started using int’s to store my variables in but that’s not what the challenge was asking so I changed things up a bit to fit the challenge. Anyways, here’s my code, and I don’t use the modern C technique ( float = ) I just use what the book taught me so far.

``````#include <stdio.h>

int main(int argc, const char * argv[])
{
float chal1;

chal1 = 15.6;

float chal2;

chal2 = 23.2;

printf("The two floats equals %f", chal1 + chal2);

double sum;
sum = chal1 + chal2;

printf("Together with the double they equal %f", add + sum);

return 0;
}``````

I could probably have used something else for the sum instead of the double but I couldn’t think of anything else to use that could store the values together, assuming I can’t use int.

I notice one error but i am unsure if you intentionally did that.

the values for the variable are incorrect.

The logic you used was correct
here is another way. this is how i solved it

``````#include <stdio.h>

int main(int argc, const char * argv[])
{

// Declare the variables
float   f_Num1,  f_Num2;
double  d_Sum;

// Initialize variables
f_Num1 = 3.14;
f_Num2 = 42.0;
d_Sum = f_Num1 + f_Num2;

// Print the sum
printf( "The sum of %f and %f is %f . \n" , f_Num1 , f_Num2 , d_Sum);

return 0;
}``````

Hope this helps…
