Programming Codes

#include<stdio.h> #include<cs50.h> int main() {     string name = get_string("What is your name?\n"); //To take user name     printf("Hello %s\n", name); //To print name }

→ A C++ program by me in which you can get the day of any given date. I have written this code by using some mathematical formulas of finding day using a given date, if you find any error or if you want to give me any suggestion then please let me know. #include<iostream> using namespace std; int main() { int date,month,year; int yc,mc,cc,dn,lyc; cout<<"Enter Date, Month and Year to know the Day:"; cin>>date>>month>>year; if(month>12 || date>31) { cout<<"Wrong input"; } else{ //for year int h=year%100; yc=(h+(h/4))%7; //for leap year if(year%4 ==0) { if(year%100 ==0) { if(year%400 == 0) { lyc=1; } } else { lyc=1; } } if(lyc==1) { if(month>2) { lyc=0; } else { lyc=1; } } //for month if(month==01 || month ==10) { mc=0; } else if(month==05) { mc=1; } else if(month==8) { mc=2; } else if(

→ A simple Java program to print * in a pattern. class Star { public static void main(String args[]) { int i,j; for(i=0;i<5;i++) { for(j=0;j<=i;j++) { System.out.print("*"); } System.out.print("\n"); } } } Output: * ** *** **** *****

→ This program will help you to learn how to implement an array in C. #include<stdio.h> int main() {   int arr[5]; //declaration of an array with maximum five values   int i;   printf("Enter five numbers:");   for(i=0;i<5;i++)   {      scanf("%d",&arr[i]);  //This line will take input in array from index zero to five i.e arr[0] to arr[4]   }   printf("Your numbers are:");   for(i=0;i<5;i++)   {     printf("%d  ",arr[i]);   }   return 0; } Output: Enter five numbers:5 6 9 8 12 Your numbers are:5  6  9  8  12

→ A simple calculator using C language. In this, you can add, multiply, divide and subtract any two number. #include<stdio.h> int main() {    float a,b,c;    char d;    printf("Enter:");    scanf("%f  %c %f",&a,&d,&b);    if(d=='+')    {     c=a+b;     printf("%.2f",c);    }    else if(d=='-')    {     c=a-b;     printf("%.2f",c);    }    else if(d=='*')    {     c=a*b;     printf("%.2f",c);    }    else if(d=='/')    {     c=a/b;     printf("%.2f",c);    } } Output: Enter:  9/4              2.25

→ Program to take input from the user- integer, char, string, decimal, and to print all values. #include<stdio.h> int main() {   int a;   char b;   char c[10];   float d;   printf("Enter interger value:");   scanf("%d",&a);   printf("\nEnter a character:");   scanf(" %c",&b);   printf("\nEnter a name:");   scanf("%s",&c);   printf("\nEnter decimal value:");   scanf("%f",&d);   printf("\nInterger value is %d ",a);   printf("\nYour Character is %c ",b);   printf("\nGiven name is %s ",c);   printf("\nDecimal value is %f ",d);   return 0; }
