Write a C program which asks the user for a number between 1 to 9 and shows the number. If the user inputs a number out of the specified range, the program should show an error and prompt

the user for a valid input ?

Program: Program for accepting a number in a given range.

#include

int getnumber();

int main() {

int input = 0;

//call a function to input number from key board

input = getnumber();

//when input is not in the range of 1 to 9,print error message

while (!((input <= 9) && (input >= 1))) {

printf("[ERROR] The number you entered is out of range");

//input another number

input = getnumber();

}

//this function is repeated until a valid input is given by user.

printf("\nThe number you entered is %d", input);

return 0;

}/

/this function returns the number given by user

int getnumber() {

int number;

//asks user for a input in given range

printf("\nEnter a number between 1 to 9 \n");

scanf("%d", &number);

return (number);

}

Output:

Enter a number between 1 to 9

45

[ERROR] The number you entered is out of range

Enter a number between 1 to 9

4

The number you entered is 4

Explanation:

getfunction() function accepts input from user. 'while' loop checks whether the number falls within range or not

and accordingly either prints the number(If the number falls in desired range) or shows error message(number is

out of range).
