Question

Write a program to dynamically allocate memory to integer, float, and character type

of data. Initialise the value of float during the compile time, and the value of integer

and character must be entered during the execution time.​

Answer 1

Answer:

I am writing the program in C language.

#include <stdio.h>

#include <stdlib.h>

int main()

{

   int *i;

   char *c;

   float *f;

   i=(int*)malloc(1*sizeof(int));                 /*Dynamically allocating Memory*/

   c=(char*)malloc(1*sizeof(char));          /*Dynamically allocating Memory*/

   f=(float*)malloc(1*sizeof(float));           /*Dynamically allocating Memory*/

   *f = 95.7256;                                         /*Initializing value of float*/

   printf("Enter an integer value: ");

   scanf("%d",i);           /*Value of integer to be entered at execution time*/

   

   printf("Enter a character value: ");

   scanf(" %c",c);       /*Value of character to be entered at execution time*/

 

   printf("Values entered are : %d, %c, %.2f",*i,*c,*f);

   

   /*Allocated memory made free*/

   free(i);

   free(c);

   free(f);

   return 0;

}

Answer 2

Python program to dynamically allocate memory to integer, float, and character type  of data.

Language used : Python Programming

Program :

x=int(input("Enter an integer : "))

y=0.987

z=input("Enter a character : ")[0]

print("Integer value is : ",x, " Float value is : ", y," Character value is : ",z)

Input :

Enter an integer : 345

Enter a character : g

Output :

Integer value is :  345  Float value is :  0.987  Character value is :  g
