scanf("%s",a);
printf("You have Entered: ");
printf("%s",a);
}
52. String- scan a sentence from keyboard
#include<stdio.h>
main()
{
char a[30];
printf("Enter a word:");
scanf("%[^\n]",a);
printf("You have Entered: ");
printf("%s",a);
}
53. String- take a sentence from keyboard (using gets and puts)
#include<stdio.h>
main()
{
char a[30];
printf("Enter a word:");
gets(a);
printf("You have Entered: ");
puts(a);
}
54. Pointer- Understanding pointer (Access the value of a variable using pointer
#include<stdio.h>
main()
{
int a;
int *p;
a=10;
p=&a;
printf("The value of a= %d\n",a);
printf("The address of a= %u\n",&a);
printf("The address of a= %u\n",p);
printf("The value of a= %d\n",*p);
}
55. User Defined Function- Sum
#include<stdio.h>
int sum(int a,int b);
main()
{
int a,b;
sum(2,3);
sum(10,20);
sum(30,40);
}
int sum(int a,int b)
{
printf("sum= %d+ %d = %d\n",a,b,a+b);
}
56. User Defined Function- Design a mini calculator
#include<stdio.h>
int sum(int a,int b){printf("sum= %d + %d = %d\n",a,b,a+b);}
int sub(int a,int b){printf("sub= %d - %d = %d\n",a,b,a-b);}
int multi(int a,int b){printf("multi= %d * %d = %d\n",a,b,a*b);}
int div(int a,int b){printf("div= %d / %d = %d\n",a,b,a/b);}
main()
{
int a,b,option;
printf("Enter an option:\n1.sum\n2.sub\n3.multi\n4.div\n");
scanf("%d",&option);
printf("Enter a:"); scanf("%d",&a);
printf("Enter b:"); scanf("%d",&b);
if(option==1) {sum(a,b);}
else if(option==2){sub(a,b);}
else if(option==3){multi(a,b);}
else if(option==4){div(a,b);}
else{printf("Sorry. Please try again\n");}
}
57. C++ (Print name, ID, Dept, University
#include<iostream>
using namespace std;
main()
{
cout<<"MUBIN"<<endl<<"1103043"<<endl<<"EEE"<<endl<<"KUET"<<endl;
}
58. C++ (Find sum)
#include<iostream>
using namespace std;
main()
{
int a,b,sum;
cout<<"Enter a number:";
cin>>a;
cout<<"Enter another number:";
cin>>b;
sum=a+b;
cout<<"sum="<<a<<"+"<<b<<"=o"<<sum;
}
59. Write a program in C++ to understand Object Oriented Programming (OOP)
60. Understanding OOP
//using same function in different class
#include<iostream>
using namespace std;
class biral
{
public:
void name(){cout<<"WHITE CAT"<< endl;}
void barking(){cout<<"MEW MEW..."<< endl;}
};
class sagol
{
public:
void name(){cout<<"LALTU"<< endl;}
void barking(){cout<<"VA VA....."<< endl;}
};
class goru
{
public:
void name(){cout<<"MOHESH"<< endl;}
void barking(){cout<<"HUMBA HUMBA...."<< endl;}
};
main()
{
biral obj1;
sagol obj2;
goru obj3;
obj1.name();
obj1.barking();
obj2.name();
obj2.barking();
obj3.name();
obj3.barking();
}
