Question

Rewrite the following loops without using the enhanced for loop construct. Here, values is an array of floating-point numbers.

a. for (double x : values) { total = total + x; }

b. for (double x : values) { if (x == target) { return true; } }

c. int i = 0;

for (double x : values) { values[i] = 2 * x; i++; }

Answer 1

a. 
for (int i = 0; i < values.length; i++) {
    total = total + values[i]; 
}

b. 
for (int i = 0; i < values.length; i++) {
    if (x == values[i]) {
        return true; 
    }
}

c. 
int i = 0;
for (int i = 0; i < values.length; i++) {
    values[i] = 2 * values[i];
}
