Question

Given two variables iVal and fVal, containing respectively an integer and a float value, write a statement that writes both of their values to standard output in the following format: i=iVal f=fVal.

For example, if iVal is assigned 5 and fVal is assigned 2.4, the statement should print the following:

i=5 f=2.4

Hi Maggie!

Did this question happen to specify a language that this should be implemented in? That will determine the actual implementation.

Regardless, the general idea is that this question is printing an integer and a double to the console. Each language has a print function which can accomplish this. Some languages, such as Python will take care of the formatting of integers and doubles itself, while a language like C will need a format string to determine which one is an integer and which is a double.

For Python, you can just use the print function.

iVal = 5

fVal = 2.4

print("i=" + str(iVal), "f=" + str(fVal))

In C, you would need to specify the types of iVal and fVal in the printf statement.

#include "stdio.h"

int main()

{

int iVal = 5;

float fVal = 2.4;

printf("i=%i f=%g\n", iVal, fVal);

return 0;

}

In this case "%i" represents an integer and "%g" represents a float with the trailing zeros suppressed. Using "%f" instead would result in "i=5 f=2.400000".
