Question

I need help writing a C programming code.

I am trying to create a program that returns ANY given number's decimal value as an Integer (Whole number).

Examples:

User input: 0.35 Output: 35

User input: 1.465 Output: 465

User input: 10.6054 Output: 6054

float.c 1 #include<stdio.h> #include<math.h> //math header file for pow() function 2 3 4. 5 6 7 8. 9 10 11 12 int main() { // declaring temporary variables double number, diff, temp_diff; int num, result = 0; // taking input from user and stroring it in number variable scanf("%1f", &number); // converting number into integer type and storing in num variable num = (int)number; // storing decimal value by substracting integer from input number diff = number - num; // stroring decimal value in another temporary variable temp_diff = diff; // making diff greater than zero by multiply it with 10(base) diff *= 10; // iter variable for storing count of numbers after decimal point int iter = 0; // while loop for counting numbers after decimal point // condition is converting diff into integer type, which is true until number is not zero 13 14 15 16 17 18 19 20 21

22 23 24 25 26 while((int)diff){ // incrementing iter by 1 iter += 1; // storing decimal value in diff diff = diff - (int)diff; diff *= 10; } // stroring resultant integer in by multiplying decimal value with 10 power iters result = (int)( temp_diff * pow(10, iter)); printf("%d", result); 27 28 29 30 31 32 }

C:\Users\krishna\Downloads>gcc -o float float.c C:\Users\krishna\Downloads>float 0.35 35 C:\Users\krishna\Downloads>float 1.465 465 C:\Users\krishna\Downloads>float 10.6054 6 C:\Users\krishna\Downloads>.

Raw_code:

#include<stdio.h>
#include<math.h> //math header file for pow() function

int main(){
// declaring temporary variables
double number, diff, temp_diff;
int num, result = 0;
// taking input from user and stroring it in number variable
scanf("%lf", &number);
// converting number into integer type and storing in num variable
num = (int)number;
// storing decimal value by substracting integer from input number
diff = number - num;
// stroring decimal value in another temporary variable
temp_diff = diff;
// making diff greater than zero by multiply it with 10(base)
diff *= 10;
// iter variable for storing count of numbers after decimal point
int iter = 0;
// while loop for counting numbers after decimal point
// condition is converting diff into integer type , which is true until number is not zero
while((int)diff){
// incrementing iter by 1
iter += 1;
// storing decimal value in diff
diff = diff - (int)diff;
diff *= 10;
}
// stroring resultant integer in by multiplying decimal value with 10 power iters
result = (int)( temp_diff * pow(10, iter));
printf("%d", result);
}

sorry: it doesn't work for last one
