Question

Write the output of the following segment of code and explain your results. int x=7, y=4, z; float z1, z2, z3; z1=x/y; z2=(float)(x/y); z3=(float)x/y; z=x/y; System.out.printf("z=%d z1=%5.2f z2=%5.2f z3=%5.2f \n}, z, z1, z2, z3);

Answer 1

int x = 7, y = 4, z;
       float z1,z2,z3;
      
       // x/y is 1.75 but integer by integer division gives an integer, thus x = 7/4 = 1
       // assigned to z1 and converted to float , thus z1 = 1.00
       z1 = x/y;

       // x/y is 1.75 but integer by integer division gives an integer, thus x = 7/4 = 1
       // which is then converted to float and assigned to z2
       // thus z2= 1.00
       z2 = (float)(x/y);

       // (float)x = 7.00, divided by y =4 , result is assigned to z3
       z3 = (float)x/y;

       // x/y is 1.75 but integer by integer division gives an integer, thus x = 7/4 = 1
       // assigned to z
       z = x/y;

       System.out.printf("z=%d z1=%5.2f z2=%5.2f z3=%5.2f \n",z,z1,z2,z3);

/*
output:
z=1 z1= 1.00 z2= 1.00 z3= 1.75
