Question

Write a program using Visual Studio 2017 that accepts four (4) lines of input:

• The first line contains a float value in 4.2f format • The second line contains a char value

• The third line contains a 4-digit int value

• The fourth line contains a char value and then displays all of the input on a single line

Phone Number

Write a program that accepts a phone number of the form +1(xxx)-xxxxxxx where x is a digit, and displays the sum of all digits (x's) in the phone number.

SUBMIT BOTH PIECES IN ONE FILE LAB2.C

Answer 1

Please find both the pieces in C program below:-

#include<stdio.h>

#include<conio.h>

void displaySum(char phone[]){

int n1 = phone[3] - '0';

int n2 = phone[4] - '0';

int n3 = phone[5] - '0';

int n4 = phone[8] - '0';

int n5 = phone[9] - '0';

int n6 = phone[10] - '0';

int n7 = phone[11] - '0';

int n8 = phone[12] - '0';

int n9 = phone[13] - '0';

int n10 = phone[14] - '0';

int sum = n1 + n2+n3+n4+n5+n6+n7+n8+n9+n10;

printf("sum of all digits (x's) in the phone number: %d\n", sum);

}

int main(int argc, char* argv[]){

system("cls");

char phone[20];

float f1 = 4.2f;

char c1 = 'A';

int i = 1234;

char c2 = 'Z';

printf("\n%.2f %c %d %c", f1, c1, i, c2);

printf("\nEnter Mobile Number in the format(+1(xxx)-xxxxxxx): ");

scanf("%s", &phone);

displaySum(phone);

system("PAUSE");

return 0;

}

The output is attached below:-
