If Statement in C – How to use If-Else Statements in the C Programming Language
June 13, 2022 - You start an if statement using the if keyword. Inside parentheses, you include a condition that needs checking and evaluating, which is always a Boolean expression. This condition will only evaluate as either true or false. The if block is denoted by a set of curly braces, {}. Inside the if block, there are lines of code – make sure the code is indented so it is easier to read. Next, let’s see a practical example of an if statement.

C If ... Else Conditions
In the example above we use two variables, x and y, to test whether x is greater than y (using the > operator). As x is 20 and y is 18, the condition is true, so the program prints "x is greater than y". Since the condition in an if statement must be either true or false, you can store the result in a boolean variable instead of writing the comparison directly:

C - The if-else Statement
The if-else statement offers an alternative path when the condition isn't met. The else keyword helps you to provide an alternative course of action to be taken when the Boolean expression in the if statement turns out to be false.

You have enter wrong datatype when comparing the choice (int type) with a string text. In C/C++ unlike dynamic programming language, you cannot compare int with strings without properly converting either of them. You use strcpy for comparing string and == for comparing int.
Then your programming will run.

I'm not sure what your program is trying to do, but let me concentrate on the few obviously incorrect lines.
First, in
int Choice;
scanf ("%s", &Choice);
you have the wrong type for Choice: it is "int" whereas it should be a static array of char (let's say char Choice[32]). In this case you also have to remove the "&" before "Choice" in the scant, so that the code becomes:
char Choice[32];
scanf ("%s", Choice);
Moreover, in
else if(Choice == "Energy") //This isnt working in my compiler.
you are trying to compare two strings with the operator "==". This does not work in C. You should use the function "strcmp" the following way:
#include<string.h>
[...]
else if(strcmp(Choice, "Energy")==0)
You'd even better use the following to prevent any buffer overflow
else if(strncmp(Choice, "Energy", 32)==0)
(replace 32 with the maximum number of elements in Choice)
Edit Note that you should change the first comparison too from
if(Choice == 2817)
to
if(strncmp(Choice, "2817", 32))
because Choice is not an int anymore...
