1- what is library function...?list any 10 library functions.
2- write down the type casting process.​(choose the best answer)

Answer 1

Answer:

hope it's help you

Explanation:

In this tutorial, you'll learn about the standard library functions in C. More specifically, what are they, different library functions in C and how to use them in your program.

C Standard library functions or simply C Library functions are inbuilt functions in C programming.

The prototype and data definitions of these functions are present in their respective header files. To use these functions we need to include the header file in our program. For example,

If you try to use print without including the stdio.h header file, you will get an error.

Answer 2

Answer:

1)

The function is defined in the math. h header file. #include <stdio.h> #include <math.h> int main() { float num, root; printf("Enter a number: "); scanf("%f", &num); // Computes the square root of num and stores in root. root = sqrt(num); printf("Square root of %.2f = %.2f", num, root); return 0

2)

Although casting is one of the oldest known manufacturing techniques, modern advances in casting technology have led to a broad array of specialized casting methods. Hot forming processes, such as die-casting, investment casting, plaster casting, and sand casting, each provide their own unique manufacturing benefits. Comparing both the advantages and disadvantages of the common types of casting processes can help in selecting the method best suited for a given production run.
