Task1.

Define the function int count_nonzeros(int* tab, int len), which returns the number of elements from the tab array that are not zero. The board is len long. (3p.)

Example call:

int data[10]={0.8,0.7,0.6,0.5,0.4};
printf("%d\n", count_zeros(date, 10));

Standard output: 5

Task2.

Define the function float med(float a, float b, float c), which will return the middle value of its 3 parameters a, b, c. (2p.)

Example call:

float a=4.5, b=10.5, c=12.2;
printf("%f\n", med(a,b,c));

Standard output:

10.5
