How do you write a program in c to calculate age?

Answer 1

//program to find the age of given date of birth

#include <dos.h>

#include <stdio.h>

int main(void)

{

struct date d;

int bd,bm,by,day,m,y,cd,cm,cy;

clrscr();

getdate(&d);

printf("\t**********WELCOME TO AGE FINDER PLACE************\n");

printf("\t*************************************************\n\n");

cd=d.da_day;

cm=d.da_mon;

cy=d.da_year;

printf("Enter the birthe date : ");

scanf("d%d",&bd,&bm,&by);

{

if(cd<bd)

{

cm=cm-1;

cd=cd+30;

day=cd-bd;

}else

day=d.da_day-bd;

}

{

if(cm<bm)

{

cy=cy-1;

cm=cm+12;

m=cm-bm;

}else

m=d.da_mon-bm;

}

y=cy-by;

printf("your age is:-\n");

printf("year=%d\tmonth=%d\tday=%d\n",y,m,day);

getch();

}

Answer 3

#include<stdio.h>

#include<conio.h>

void main()

{

long int a,age;

clrscr();

printf("Enter your age :");

scanf("%ld",&age);

if(age<=0)

printf("Enter valid data only\n");

else

{

a=(age*365*24*60*60);

printf("Before conversion:\n");

printf("\tAge in years is: %ld\n",age);

printf("After conversion:\n");

printf("\tAge in seconds is: %ld\n",a);

}

getch();

}

Answer 4

HERE IS A PROGRAMME THAT WRITTEN BY "ARJUN BHARASAGAR". BY HELP OF THIS PROGRAMME YOU CAN KNOW YOUR CURRENT AGE.

IF YOU WANT TO LEARN MORE ABOUT ANY DOUT IN C OR C++. PLESE MAKE FREINRSHIP BY ORKUT FREE SO THAT I WILL MAIL OR SAY YOU AS I KNOW.

I WILL SAY YOU THE PROCESS OF THIS C PROGRAMME.

# include<stdio.h>

# include<conio.h>

void main()

{

int bd,bm,by,cd,cm,cy,ad,am,ay;

clrscr();

printf("\n\t enter the current date :");

scanf("%d%d%d",&cd,&cm,&cy);

printf("\n\t enter the date of birth : ");

scanf("%d%d%d",&bd,&bm,&by);

if(cd<bd)

{

cm=cm-1;

cd=cd+30;

}

if(cm<bm)

{

cy=cy-1;

cm=cm+12;

}

ad=cd-bd;

am=cm-bm;

ay=cy-by;

printf("\n\t Your age is :%d,%d,%d",ay,am,ad);

getch();

}

Answer 5

/*program to calculate the age*/

#include<stdio.h>

#include<conio.h>

int age();

void main()

{

int yr,a;

printf("enter your year of birth\n");

scanf("%d",&yr);

a=age(yr);

printf("\nYour age is %d",a);

}

int age(int yr)

{

int x,y;

printf("enter the current year");

scanf("%d",&x);

y=x-yr;

return (y);

}
