1, (*) calculates the decimal 42 conversion to binary, octal, hexadecimal corresponding value.

<42 Two-stage 100,108-binary 526-0x2>

2 Calculating decimal values for binary 11010110

< decimal 112>

3 Calculating decimal values for octal 075

<61>

4 Calculating the hexadecimal 0xa8 corresponding decimal value <168>

5 Print the following graphic:

#include <stdio.h>

int main (int argc, const char * argv[])

{

printf ("* \ n");

printf ("* * \ n");

printf ("* * * \ n");

}

6 Write a program that requires the user to enter a dollar amount and then show the corresponding amount after increasing the%5 tax rate. The format is as follows: Enter an amount:100.00 with tax added:$105.00

#include <stdio.h>

int main (int argc, const char * argv[]) {

float A, B;

printf ("Enter an amount:");

scanf ("%f", &a);

B=1.05*a;

printf ("With tax added:$%.2f\n", b);

return 0;

}

7 Enter two real numbers a and b from the keyboard, and a percentage of B for output a. Retain 2 digits after the decimal point. For example: Input 1 and 4, output: 25%

#include <stdio.h>

int main (int argc, const char * argv[]) {

float A, B; printf ("Please enter two numbers:");

scanf ("%f%f", &a,&b);

printf ("%.2f\n", A/b);

printf ("Output:%.2f%%", a/b*100);

return 0;

}

8 Write a program that asks the user to enter a dollar amount and then shows how to pay with a minimum of $20, $10, $5 and $1: Enter a dollar Amoun t:93 $ bills:4 $ bills:1 $ bills:0 Bills:3

#include <stdio.h>

int main (int argc, const char * argv[]) {

int a,b,c,d,e;

printf ("Please enter a number:");

scanf ("%d", &a);

B=A/20;

printf ("$ bills:%d\n", b);

C= (A-B*20)/10;

printf ("$ bills:%d\n", c);

D= (A-B*20-C*10)/5;

printf ("$ bills:%d\n", d);

E= (a-b*20-c*10-d*5)/1;

printf ("$ bills:%d\n", e);

return 0;

}

9 Enter two integers, print these two numbers of the and, difference, product, remainder

#include <stdio.h>

int main (int argc, const char * argv[]) {

int A, B;

printf ("Please enter two integers:");

scanf ("%d%d", &a,&b);

printf ("%d\n", a+b);

printf ("%d\n", A-B);

printf ("%d\n", a*b);

printf ("%d\n", A/b);

printf ("%d\n", a%b);

return 0;

}

10 Find the ASCII code table, with%d output characters, and output integers with%c.

#include <stdio.h>

int main (int argc, const char * argv[]) {

char a = ' a ';

printf ("Please enter:");

scanf ("%c", &a);

printf ("%d\n", a);

printf ("%c\n", a);

}
