Question

1. Create a program (in C, not C++) called lab3.c that declares the following variables and displays their values:

   1. Declare a character variable with value 'a', and display the character using printf with %c format. Then add a second printf that displays the character with a %d format.

   2. Declare a short int variable with a value set to the maximum value of a short int (the maximum value for whatever machine I happen to use to grade your assignment - so use the correct limits.h constant). Display the value using printf with %d format. Please refer to this link for more information on constants from limits.h.

   3. Declare a double variable with a value set to positive infinity. Display the value using printf with the %f format.

   4. Prompt the user and accept the following 4 types of values from a single input line: char int char float

   5. Display the values that were read in (d)

   6. Prompt the user and accept the following types of values from a single input line: char float int char

   7. Display the values that were read in (f)

   8. Prompt the user and accept an integer value

   9. Display the value read in (h) in a right-justified field of width 15, with leading zeroes.

   10. Prompt the user and accept a float value

   11. Display the value read in (j) in a right-justified field of width 15, with 2 decimal points of precision, and leading spaces

THIS NEEDS TO BE C, C IS DIFFERENT THAN C++

Answer 1

Here is the completed code for this problem. Comments are included, go through it, learn how things work and let me know if you have any doubts or if you need anything to change. If you are satisfied with the solution, please rate the answer. Thanks

#include<stdio.h>

#include<limits.h>

#include<math.h>

int main(){

                //Declare a character variable with value 'a', and display the character

                char c='a';

                printf("%c\n",c); //using %c

                printf("%d\n",c); //using %d

               

                //Declare a short int variable with a value set to the maximum value of a short int

                short s=SHRT_MAX;

                //displaying the value

                printf("%d\n",s);

               

                //Declare a double variable with a value set to positive infinity

                double d=INFINITY;

                //Display the value using printf with the %f format.

                printf("%f\n",d);

               

               

                char c1, c2;

                int i1;

                float f1;

                //Prompt the user and accept the following 4 types of values from a

                //single input line: char int char float

                printf("Enter a char, int, char and float: ");

                scanf(" %c %d %c %f",&c1,&i1,&c2,&f1);

                //Display the values that were read

                printf("%c %d %c %f\n",c1,i1,c2,f1);

               

                //Prompt the user and accept the following types of values from a

                //single input line: char float int char

                printf("Enter a char, float, int and char: ");

                scanf(" %c %f %d %c",&c1,&f1,&i1,&c2);

                //Display the values that were read

                printf("%c %f %d %c\n",c1,f1,i1,c2);

               

                //Prompt the user and accept an integer value

                printf("Enter an integer value: ");

                scanf("%d",&i1);

                //Display the value read in (h) in a right-justified field

                //of width 15, with leading zeroes.

                printf("%015d\n",i1);

               

                //Prompt the user and accept a float value

                printf("Enter a float value: ");

                scanf("%f",&f1);

                //Display the value read in (j) in a right-justified field of width 15, with 2 decimal

                //points of precision, and leading spaces

                printf("%15.2f\n",f1);

                return 0;

}
