-What code will initialize an array with even-numbered elements set to 4.99 and the odd-numbered elements set to 7.99? (Elements are numbered at offsets 0, 1, 2, ...)

for (int i=1; i<=25; ++i) { if (i % 2) array[i] = 7.99; else array[i] = 4.99; }

array[0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24] = 4.99; array[1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25] = 7.99;

for (int i=0; i<25; ++i) { if (i % 2) array[i] = 4.99; else array[i] = 7.99; }

for (int i=0; i<25; ++i) { array[i] = 4.99; array[i+1] = 7.99; }

for (int i=0; i<25; ++i) { if (i % 2) array[i] = 7.99; else array[i] = 4.99; }
