Write an if/else statement that compares the value of the variables soldYesterday and soldToday, and based upon that comparison assigns salesTrend the value - 1 or 1. - 1 represents the case where soldYesterday is greater than soldToday; 1 represents the case where soldYesterday is not greater than soldToday.

if (soldYesterday > soldToday) {

salesTrend = - 1;

} else if (soldToday > soldYesterday) {

salesTrend = 1;

}

Explanation:

The if/else statement is more explicit. The first if condition check if soldYesterday is greater than soldToday, if true, then - 1 is assigned to salesTrend.

Else if soldToday is greater than soldYesterday, if true, then 1 is assigned to salesTrend.
