QUESTION 1
A C program contains the following declarations and initial assignments:
int i=15, j=8, k=2;
float x= 0.5 , y= -1.0, z;
char c=โsโ, s=โxโ;
/* character โsโ is 115, and โxโ is 120 */
Use the variables initially assigned to the variables for each expression to determine the
value of each the following expressions:
(8*i-2*j+21)%(2*s-c)
+j - ++y/-k;
c = = s;
('x'-'s')/(j=x=5)
i*j> โxโ && โsโ= =115
What will be output of the following printf statements for i = 91, x = 987.4321, id=204001
1. printf("|%-4d|%3.3d|%2d |",x, x, x);
2. printf("|%.0f|%-8.3f|%6.1f |",y, y, y);
3. printf(" \"student:Nadi Lutfi\" \n \" \t :ID%d\" \n ",id);
