#include <stdio.h>
#include <stdlib.h>

/* Write a function which accepts an integer value as input, and returns an integer which is the cube of that input */
int l(int);
int main(int argc, char *argv[]) {
 printf("vao X= ");
 int x;
 scanf("%d",&x);
 printf("x^3 = %d",l(x)); 
 printf("\n\n\n");
 system("pause");
 return 0;
}
int l(int x){
 int y = x*x*x;
 return y;

2. Write a function that accepts a char as input and returns true if the char is a digit from 0 to 9 or false if the character is not a digit from 0 to 9

#include <stdio.h>
#include <stdlib.h>
/* Write a function that accepts a char as input and returns true 
if the char is a digit from 0 to 9 or false if the character is not a digit from 0 to 9 */

 printf("vao ki tu : ");
 char x;
 scanf("%c",&x);
 if (tf(x)) printf("%c nam giua 0 - 9",x);
  else printf ("%c khong nam giua 0 - 9",x); 
 printf("\n\n\n");
 system("pause");
 return 0;
}
int tf(char x){
 int y;
 if (x >= '0' && x<= '9') y = 1;
 else y = 0;
 return y;

 int i =x;
 if (i > y) i = y;
 if (i > z) i = z;

4. Write a function that, given a letter of the alphabet, returns true if the letter is a vowel (lower or uppercase) and returns false if the letter is not a vowel.

#include <stdio.h>
#include <stdlib.h>
/* Write a function that, given a letter of the alphabet, 
returns true if the letter is a vowel (lower or uppercase) and returns false if the letter is not a vowel. */
int t(char);
int main(int argc, char *argv[]) {
 printf ("vao 1 chu: ");
 char x;
 gets(&x);
 if (t(x)) printf ("%c la nguyen am",x);
  else printf ("%c khong phai la nguyen am",x);
 printf("\n\n\n");
 system("pause");
 return 0;
}
int t(char x){
 int t;
 if (x=='u'||x=='U'||x=='e'||x=='E'||x=='o'||x=='O'||x=='a'||x=='A'||x=='i'||x=='I') t= 1;
  else t=0;
 return t;
