Question

C PROGRAMMING

1. Write a C Language inline function that computes the cube of float X, if X is greater than 1 and X is less than 100. Put the inline function in a main program that reads X from the keyboard, calls the function, and then outputs the result.

2. Show an empty statement and detail what it does?

3. A collection of predefined functions is called a

1. Database                    C) Subroutine                       E) None of these
2. Library                       D) Directive

4. T___ F___ A function should be created if the code will be used often in the program or in future programming.

Answer 1

#include <stdio.h>
inline float cube(float x){
    return x*x*x;
}

int main() {
    float a;
    float result;
    printf("Enter the value..\n");
    scanf("%f",&a);
    printf("Entered value is: %f\n",a);
    if(a>1 && a<100){
        result = cube(a);
        printf("Cube result: %f\n",result);
    }
    else{
        printf("The entered value should be greater than 1 and less than 100! Try again!");
    }
    
    return 0;
}

#include <stdio.h>


int main() {
char text[25] = "Miracle can happen";
int i;

for(i = 0; text[i] != 'q'; i++)
    ;//empty statement
    //If we have 'q' in our string it will not go inside the loop
    
    return 0;
}

//When we want to find the index of first occurrence of a given character in a string in our case its q.

#include <stdio.h>


int main() {

for(;;;) //empty loop it will run  forever.
    
}

3. A collection of predefined functions is called a Library.

As the C in-built functions are collected and placed together in a library every library does a specific task.

for example stdio.h takes case of input output tasks.

database is not the answer as no predifined database s their in C.

Subroutine is kind-of a function which user creates with specific instructions associated with a name.

Directives are the initial lines of program begain with # it is to include some library etc.

4. A function should be created if the code will be used often in the program or in future programming - TRUE

because when we need some lines of code to run often then without writing the same code again and again we write it separately as a function and we call that function whenever we want to run those specific codes.
