Error messages

[piczim]

I have two error messages in the code below that I have no idea what they mean. Knot knowing what they mean means that I am unable to fix them.

The errors are

error: switch quantity not an integer
error case label does not reduce to an integer constant

  #include <stdio.h>

 int main(int argc, char *argv[])
 {
 float inputamount, result;

 printf("\n\n Enter amount to be converted"); 
 printf("\n in the form  SA, where the");
 printf("\n where the two letters represent");
 printf("\n a country.");
 printf("\n ad = Australian dollars.");
 printf("\n gb = British Pounds.");
 printf("\n jp = Japenes yen.");
 printf("\n vd= Vitnames dollars.");
 printf("\n\n Enter amount to convert: ");

 switch(inputamount)
 {
 
case "ad":
 result = inputamount * 1.044;
break;

 case "gb":
 result = inputamount / 0.63;
 break;

 case "jp":
 result = inputamount * 95.057;

 case "vd":
 result = inputamount * 2.106;

break;

The messages mean what they say.

Here switch(inputamount) should be an integer, but it is declared as float inputamount.

In the case statement such as case "ad":, the value "ad" isn't an integer and can't be converted to an integer.

In any case, even if the compiler accepted this code, it would mean a variable of type float was being compared with a string of characters, which doesn't make much sense. So really the compiler is helping you by pointing out that what you are asking it to do doesn't make sense.
