Question

1)Create a conditional expression that evaluates to string "negative" if userVal is less than 0, and "positive" otherwise. Example output when userVal = -9 for the below sample program:

-9 is negative.
#include
#include

int main(void) {
char condStr[50] = "";
int userVal = 0;

userVal = -9;

strcpy(condStr, /* Your solution goes here */);

printf("%d is %s.
", userVal, condStr);

return 0;
}

2)

Using a conditional expression, write a statement that increments numUsers if updateDirection is 1, otherwise decrements numUsers. Ex: if numUsers is 8 and updateDirection is 1, numUsers becomes 9; if updateDirection is 0, numUsers becomes 7. Hint: Start with "numUsers = ...".

#include

int main(void) {
int numUsers = 0;
int updateDirection = 0;

numUsers = 8;
updateDirection = 1;

/* Your solution goes here */

printf("New value is: %d
", numUsers);

return 0;

Answer 1

1. userVal < 0 ? "negative" : "positive"

2. updateDirection == 1 ? numUsers++ : numUsers--;

Answer 2

1:

if userVal<0

cout <<" negative":

userVale >0

cout<<"positive":

2:

if

updateDirection ==1;

numUsers++;

cout<<"numUser"

else

numUser--;

cout<<"numUser";
