Question

Please help this out with all

Purpose: Learn how to get input and print out formatted results using scanf and printf separately in C. 1) Write a C program getPhone Number:c that accepts a phone number from the user in the form XXX-XXX-XXXX, and then displays it in the form (XXX)XXX-XXXX: Enter a phone (XXX-XXX-XXXX): 011-123-4567 You entered (011) 123-4567 Question: Execute your getPhoneNumber.c and attach a screenshot of the output. Then write the source code of getPhoneNumber.c in your answer sheet (8 points) and upload your file getPhone Number.c to iCollege. (2 points) 2) Suppose that we call scanf as follows: scanf ("%f %d %f", &x, &i, &y); Question: If the user enters 12.1 5.65 789 What will be the values of i, x and y after the call? (Assume that x and y are float variables and i is an int variable.) And explain why? Put your answer in the answer sheet. (6 points) 3) Suppose that we call scanf as follows: scanf("%d %f %d", &i, &x, &j); Question: If the user enters 10.2 8 6 What will be the values of i, x and j after the call? (Assume that i and j are int variables and x is a float variable.) And explain why? Put your answer in the answer sheet. (6 points)

Answer 1

Enter a phone 011-123-4567 you Entered(011)123-4567|

1 #include <stdio.h> 2 3. int main() { 4 int x,y,z; 5 printf("Enter a phone "); 6 scanf("%d-%d-%d",&x,&y, &z) 7 printf("\nyou entered"); 8 printf("%d)%d-%d",x,y,z); 9 10 1 11 1/code 12 return 0; 13}
1)Above Input and output for Question 1

in this we are storing 3 variable separately first varaible x for first varible 3 digits,seond variable y store 3 digits, and last z stores 4 digits.

float x,y; 8 1 #include <stdio.h> 2 3- int main() { 4 5 int i; 6 scanf("%f %d %f",&x,&i,&y); 7 printf("%f %d %f",x, i,y; //code typedef keyword 9 return 0; 10} typename keyword dynamic_cast keyword typeid keyword try keyword array snippet decltype keyword _Imaginary keyword

Time(sec): 0 Memory(MB): 1.5603218725586 Output: Copy 12.100000 5 789.000000
2) Above is code and output for 2nd question in x is variable float so it will print 12.10000 by default float has 6 digit precision after decimal

i is varibale of integer type, so it will print only integer part and decimal will be ignored

y is float varible but we are passing it integer value so, it insert decimal point with 6 zeros.

1 #include <stdio.h> 2 3- int main() { 4 int i, j; 5 float x;] 6 scanf("%d %f %d",&i,&x,&j); 7 printf("%d %f %d", i,x,j); 8 //code 9 return 0; 10}

Time(sec): 0 Memory(MB): 1.5681227990723 Output: 10 8.000000 6
3) above is code and output for 3

in this i is variable of type integer so it will print only 10 and negelect the decimal part

x is the variable of type float it will insert decimal will with 6 zeros

j is the variabe of type int so it will print 6 only.

i hope this helps you give an upvote!!
