I would liketo know how to set the number of decimal places in the below code to 2.

#include <stdio.h>
#include <math.h>
#include <string.h>

int main()  {
int a =2;
int b =4;
int c =6;
int d =8;

int currencyOption;

printf("\n *********************************************");
printf("\n *********************************************");
printf("\n ** Enter the number from the below list    ** ");
printf("\n ** of currency you wish to convert to US$  **");
printf("\n **                                         **");
printf("\n **                                         **");
printf("\n **    1 = Australian dollars.              **");
printf("\n **    2 = British Pounds.                  **");
printf("\n **    3 = Japanese yen.                    **");
printf("\n **    4 = Vietnams dollars.                **");
printf("\n **                                         **");
printf("\n **    Enter Currency number:               **");
printf("\n **                                         **");
printf("\n *********************************************");
printf("\n *********************************************");
printf("\n");

scanf("%d", &currencyOption);
printf("\n");

float xrate;
if(currencyOption == 1) {
    xrate=1.078;
       printf("You want to convert Australian dollars to US$ \n"); }
if(currencyOption == 2) {
    xrate=0.656;
       printf("you want to convert British pounds to US$ \n"); }
if(currencyOption == 3) {
    xrate=98.309;
       printf("you want to convert Japanese yen to US$ \n"); }
if(currencyOption == 4){
    xrate=21025.0;
       printf("you want to convert vietnames dollars to US$ \n"); }

printf("\n");
printf("\n **************************************************");
printf("\n **************************************************");
printf("\n **                                              **");
printf("\n **  Enter the amount you wish to convert to US$ **");
printf("\n **                                              **");
printf("\n **************************************************");
printf("\n **************************************************");
printf("\n");


    float currencyvalue;
printf("\n");

    scanf("%f",&currencyvalue);
    int i=1;
    float result[2];

            int mult = i* 1;
    result[i] = currencyvalue * xrate * mult;
    printf("\n");
    printf("\n");
    printf(" %f To Be Converted\n\n Exchange rate of %f \n\n US$%f will be recieved\n--------------------\n", currencyvalue, xrate, result[i]); 
    printf("\n");



return 0; }

Instead of %f use something like %3.2f
This means you can print 3 digits and two digits after the decimal point.
