Question

Question (1) Write for statements that print the following sequences of values

a) 30, 20, 10, 0, –10, –20, –30

b) 15, 23, 31, 39, 47, 55

Question (2) Write a function call it cube to find the cube of each number.

Please write this in programming C language and please explain what we are doing in each step.

Answer 1

a)

#include<stdio.h>
int main()
{
int i;
for(i=30;i>=-30;i-=10) //from i=30 to -30 each time decrease i value by 10
printf("%d ",i);
}

main.c #include<stdio.h> int main() int i; for(i=30;i>=-30;i-=10) //from i=30 to -30 each time decrease i value by 10 printf("%d 4. ',i); input 30 20 10 -10 -20 -30 ... Program finished with exit code 0 Press ENTER to exit console.

b)

#include<stdio.h>
int main()
{
int i;
for(i=15;i<=55;i+=8) //from i=15 to 55 each time increase i value by 8
printf("%d ",i);
}

main.c #include<stdio.h> int main() 1. int i; for(i=15;i<=55;i+=8) //from i=15 to 55 each time increase i value by 8 printf("%d ",i);| 4 6. input 39 15 23 31 47 55 ... Program finished with exit code 0 Press ENTER to exit console.|

Question 2:

#include<stdio.h>
void cube(int);//function declaration
int main()
{
int num=5; //declare a variable num
cube(num);//call function cube
}
void cube(int n)
{
int c;
c=n*n*n;
printf("Cube of %d = %d ", n , c);

}

main.c 1 #include<stdio.h> 2 void cube (int);//function declaration 3 int main() 4- { int num=5; //declare a variable num cube(num);//call function cube 8 void cube(int n) 9- { int c; 10 11 c=n*n*n; printf("Cube of %d = %d ", n, c); 12 13 14 } input Cube of 5 = 125 ...Program finished with exit code 0 Press ENTER to exit console.
