also, details are very helpful.
code is not running correctly could mean anything.
one thing that I see immediately is that you think the first array location is 1. It isnt, its 0.
an array [7] has valid locations 0,1,2,3,4,5,6 for a total of 7 values. you want for(x = 0; x < 7; x++) to go through it. This alone is breaking your code; whatever else may also be going on in there.

when you access array[7] at location [7] or [8] it often works (runs) but what happens is that you are reading or editing memory that belongs to something else, like another variable, and from there things just go wrong.

for (int k = 1; k < 8; k++)
{
for (int b = 1; b < 4; b++)
{
cout << setw(10) << fixed << setprecision(2) << week[k][b];
