Test Suite

Test Status Code Input and Output
1   Pass
x = 1; y=1; pc=1; [sum, carry]=bin_sum_carry(pc,x,y) assert(isequal(sum,1)) assert(isequal(carry,1))

sum = 1 carry = 1

2   Pass
x = 1; y=1; pc=0; [sum, carry]=bin_sum_carry(pc,x,y) assert(isequal(sum,0)) assert(isequal(carry,1))

sum = 0 carry = 1

3   Fail
x = 1; y=0; pc=0; [sum, carry]=bin_sum_carry(pc,x,y) assert(isequal(sum,1)) assert(isequal(carry,0))

Index exceeds the number of array elements (1). Error in bin_sum_carry (line 4) sum=str2num(a(2)); Error in Test3 (line 4) [sum, carry]=bin_sum_carry(pc,x,y)

4   Fail
x = 0; y=0; pc=0; [sum, carry]=bin_sum_carry(pc,x,y) assert(isequal(sum,0)) assert(isequal(carry,0))

Index exceeds the number of array elements (1). Error in bin_sum_carry (line 4) sum=str2num(a(2)); Error in Test4 (line 4) [sum, carry]=bin_sum_carry(pc,x,y)

5   Pass
x = 1; y=1; pc=0; [sum, carry]=bin_sum_carry(pc,x,y) assert(isequal(sum,0)) assert(isequal(carry,1))

sum = 0 carry = 1
