How to Convert Integer to Strings then turn it to Floating point?

[madmhan84]

Good day everyone,

Hope you could help me on this one

The program is running but the result is far from what I want please help me... TIA

Like this one:

Input:
------------------------------------
Enter first number: 7
Enter second number: 45
------------------------------------

Output:
------------------------------------
7.45
7.00
------------------------------------

which should be my target output is:
------------------------------------
7.45
7.45
------------------------------------

#include<stdio.h>
#include<string.h>
#include<stdlib.h>
main()
{
   char str1[80],str2[80];
   int num1, num2;
   float num3;

   clrscr();

   printf("Enter first number: ");
   scanf("%d",&num1);
   printf("Enter second number: ");
   scanf("%d",&num2);

   sprintf(str1,"%d.",num1);
   sprintf(str2,"%d",num2);

   strcat(str1,str2);
   printf("%s\n",str1);

   num3 = atoi(str1);
   printf("%.2f",num3);

   getch();
}

Thanks in advanced again!:)

Check out atof

lines 17 and 18 can be combined sprintfstr1,("%d.%d", num1, num2); , then delete line 20 which calls strcat(), and delete str2 because it is not needed.
