If it runs and gives the correct result - then it is fine.

I think it will not give the correct result (or am I the one who is mistaken?). Based from my understanding, the programmer wants to solve for base raised to power. The above code, however, computes for power raised to base.

If I am right, the "red" in the ff code snippet must be changed to "green":

/* solution 1 */
scanf("%f,%d",&b,&p);
scanf("%d,%f",&p,&b);

/* or solution 2 */
printf("Enter the value as format(power,base):");
printf("Enter the value as format(base,power):");

/* Note: Either you do solution 1 or solution 2. Do not do them both. */

Correct me if I am wrong (grammatical errors too) but I think there is a logic error in this program. One more thing, variable declarations should come before any other statement. In other words, do this:

float a=1; int p; float b;
clrscr();

instead of this one:

clrscr();
float a=1; int p; float b;

Hope that helps.

Good going, spotting that base/exponent mix-up!

Where to place declarations depends on wether you're writing C or C++. For C they have to come at the beginning of the function, like you said, for C++ they can come in other places as well.

Yeah. Although I think the Turbo C 2.01 C compiler accepts main to have a void return type. It's not a good programming practice, though, I think, since the OS has no way to know whether the program terminated normally.
