scanf("%d",&num1);
printf("Enter a number 2\n");
scanf("%d",&num2);
printf("Enter a number 3\n");
scanf("%d",&num3);
if((num1>num2) && (num1>num3))
{
printf("%d is bigger\n",num1);
}
else if((num2>num1) && (num2>num3))
{
printf("%d is bigger\n",num2);
}
else
{
printf("%d is bigger\n",num3);
}
}
11. Multiplication by using addition
#include<stdio.h>
main()
{
int a,b,i,multiplication=0;
printf("Enter a,b\n");
scanf("%d%d",&a,&b);
if(b<0)
{
a=a+b;
b=a-b;
a=a-b;
}
if(a>=0)
{
for(i=1;i<=a;i++)
multiplication+=b;
}
if(a<0)
{
for(i=a;i<=-1;i++)
multiplication-=b;
}
printf("Multiplication=%d\n",multiplication);
}
12. Print company bonus on salary
#include<stdio.h>
#include<string.h>
main()
{
int i,j;
float salary,bonus;
char gender;
printf("Enter M for Male and F for Female\n");
scanf("%c",&gender);
printf("Enter Salary\n");
scanf("%f",&salary);
if(gender=='M' || gender=='m')
{
if(salary>10000)
bonus=(float)(salary*0.05);//0.05--5%
else
bonus=(float)(salary*0.07);
}
if(gender=='F' || gender=='f')
{
if(salary>10000)
bonus=(float)(salary*0.1);//0.1--10%
else
bonus=(float)(salary*0.12);
}
salary+=bonus;
printf("Bonus=%.2f\nSalary=%.2f\n",bonus,salary);
}

#include<stdio.h>
main(){
float basicPay,dearnessAllowance,houseRentAllowance,grossSalary,providentFund;
printf("Enter Basic Pay \n");
scanf("%f",&basicPay);
houseRentAllowance=0.2*basicPay;
dearnessAllowance=0.4*basicPay;
providentFund=0.12*basicPay;
grossSalary=basicPay+dearnessAllowance+houseRentAllowance+providentFund;
printf("Basic Pay=%.2f\n",basicPay);
printf("Dearness Allowance=%.2f\n",dearnessAllowance);
printf("House Rent Allowance=%.2f\n",houseRentAllowance);
