FIT100: Fluency with Information Technology

Arrays and Loops

Loops and arrays work together

•Declare an array and initialize elements to 4

var j, A = new Array(5);

for (j=0; j<5; i++) {

A[i] = 4;

}

WFI and array’s indices both start at 0

Notice what would change to have 1000 elements -- arrays and loops give power

Five elements: A[0], A[1], A[2], A[3] & A[4]
