- 2. Edit the coding so that the value of x is keyed in my the userExercise 2.0: Compile and run the program below<br /># include<stdio.h><br /># include<conio.h><br />int factorial(unsigned int number)<br />{<br /> if(number <= 1)<br /> return 1;<br /> return number * factorial(number - 1);<br />}<br />int main()<br />{<br /> int x = 5;<br /> printf(\" factorial of %d is %d\" ,x,factorial(x));<br />getch();<br />return 0;<br />}<br />Explain how the calculation work
- 3. Edit the coding so that the value of x is keyed in my the userExercise 3.0: Compile and run the program below<br />int main(){int x,y=0; printf(\" Masukkan sebarang nombor \" );scanf(\" %d\" ,&x); <br />while ( y <x){printf( \" %d\n\" , y );y++; }<br />getchar();}<br />Complete the coding
- 4. Modify while to do-while loop
- 5. Modify the while loop to for loopExercise 4.0: Compile and run the program below<br />printf(\" Enter an integer to choose a color(red=1,green=2,blue=3):\n\" );scanf(\" %d\" ,&color);switch(color){case 1: printf(\" you chose red color\n\" ); break;case 2:printf(\" you chose green color\n\" ); break;case 3:printf(\" you chose blue color\n\" ); break;default:printf(\" you did not choose any color\n\" );}<br />Complete the coding
- 6. Modify the switch case to if else selectionExercise 5.0: Compile and run the program below<br /> double circumferencecal(int rads){<br /> double x;<br /> float pi=3.1415;<br /> x=2*pi*rads;<br /> return(x);<br /> }<br />Complete the coding
