Write a program in C that reads a 3-bit desired light pattern from the 3 input switches connected to pins P2.3-P2.5 and displays the pattern on the 8 LEDs (pins P1.0-P1.7) with some ""light playing"" options based on the input from other 3 switches (pins P2.0-P2.2).

Explanation:

#include<stdio.h>

main()

{ int k=1,p,l,i;

int p2[8],p1[8];

for(i=0;i<8;i++){

p1[i]=0;

p2[i]=0;

}

while(k==1)

{

printf("enter the pin inputs from p2.3-p2.5:");

scanf("%d%d%d",&p2[3],&p2[4],&p2[5]);

printf("Press Logic 0 for on and 1 for off on switch port p2.0\n");

scanf("%d",&l);

p1[3]=p2[3];

p1[4]=p2[4];

p1[5]=p2[5];

if(l==0)

{p=1;

for(i=0;i<8;i++)

printf("p1.%d : %d\n",i,p2[i]);

printf("\n press either 1 to continue or 0 to stop :");

scanf("%d",&p);

printf("\n");

while(p==1)

{ printf("enter the pin inputs from p2.3-p2.5:");

scanf("%d%d%d",&p2[3],&p2[4],&p2[5]);

p1[3]=p2[3];

p1[4]=p2[4];

p1[5]=p2[5];

for(i=0;i<8;i++)

printf("p1.%d : %d\n",i,p2[i]);

printf("\n press either 1 to continue or 0 to stop :");

scanf("%d",&p);

printf("\n");

}

}

else

{

printf("After Rotation of pattern :\n");

else

printf("Make Rotation slow\n");

printf("Enter 1 to continue or 0 to exit:");

scanf("%d",&k);

printf("\n");

given the options, i would say your best bet is c. the modem supports up to 56 kbps, which is too low for video streaming. dial up modems use actual phone lines, which only can go up to 56 kbps as that's more than sufficient for traditional phone calls. this is also the reason why when a dial-up modem connects, you hear all those sounds. it's literally using the phone line to establish a connection.
