DIGITAL CLOCK

 In this blog I  will be providing you with the code of making a simple clock using C Language.I hope that you will like it.

 

CODE:-

 

#include<stdio.h>
#include<stdlib.h>
void print1(char *x[20]){ //This is the function for printing the output i.e. a day ahead.
char *day[20]={"Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"};
//above array is created to store the days.
char *res[1];// this array is created to store the result.
int i,flag,result;

for(i=0;i<7;i++){
    result=strcmp(x,day[i]);//This is used to compare two strings.If the two strings are same,then it will return a value0.*
    if(result==0){         //* and if not then ,it will return a non zero number.
        *res=*(day+i+1);
        flag=1;
    }
}
if(flag==1){
    printf("%s",*res);
}    
}
void print2(char*x[20]){//This is the function for printing the output i.e. today.
char*day[20]={"Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"};

char *res[20];
int i,flag,result;

for(i=0;i<7;i++){
    
    result=strcmp(x,day[i]);
    if(result==0){
        *res=*(day+i);
        flag=1;
    }
}
if(flag==1){
    printf("%s",*res);
}    
}
int main(){
    char *user[20];
    
//system("cls");
    int h,m,s,flag=0;
    double i;
    printf("Enter the time in hours  : ");
    scanf("%d",&h);
    printf("Enter the time in minutes: ");
    scanf("%d",&m);
    printf("Enter the time in seconds: ");
    scanf("%d",&s);
    printf("Enter the day: ");
scanf("%s",&user);
if(h<12){
    flag=1;
}
    start:
    for(h;h<24;h++) {
        for(m;m<60;m++) {
            for(s;s<60;s++) {
                system("cls");//This command is for clearing the previous inputs and outputs on the screen.
                system("color 4");//This is for the text color.this is completely optional
                printf("\n\n\n\t\t\t%d:%d:%d",h,m,s);
                if(h<12){
                if(flag==1){
                    printf("\n\n\t\t\tA.M.\t");
                    print2(user);//It will print the same day.
                }
                    else{
                        printf("\n\n\t\t\tA.M.\t");
                    print1(user);// It will print the next day.
                    }
            
                }
              else
                {
                    system("color 4");
                    printf("\n\n\t\t\tP.M.\t");
                        print2(user);
                }
                for( i=0;i<126299995;i++) {
                
}
                
}
s=0;// whenever the second loop ends,the value of second will become 0 and after that seconds will be counted from 0.
}
m=0;// whenever the minute loop ends,the value of minute will become 0 and after that minutes will be counted from 0.
}
h=0;// whenever the hour loop ends,the value of hour will become 0 and after that hours will be counted from 0.
goto start;// this is done, so that the clock won't stop.Otherwise the clock will stop at 23:59:59.
getch();
return 0;
