Explanation / Answer

#include<stdio.h>
int findNextElectionYear(int year){
    if(year%4 == 0) return year;
    int temp = 4 - (year % 4);
    return temp + year;
}

int getDayOn6November(int year){
    int difference = year - 2012;
    int temp;
    int day;
    if(difference > 0){
        temp = difference/4;
        temp += difference;
        day = (temp + 2) % 7;
    }
    else if(difference < 0){
        difference = -1 * difference;       
        temp = difference/4;
        if(difference % 4 != 0) temp++;
        temp += difference;
        day = (((2 - temp)%7) + 7) % 7;
    }
    else {
        day = 2;
    }
    return day;
}

int getFirstTuesday(int dayOn6Nov){
    int dayOn1Nov = (dayOn6Nov + 2) % 7;
    int temp = (9 - dayOn1Nov)% 7;
    temp = 1 + temp;
    return temp;
}

int main(){
    int year;
    printf("Enter the year: ");
    scanf("%d",&year);
    if(year < 1788 || year > 2100){
        printf("Error! Year must be in the range [1788 - 2100]!");
        exit(0);
    }
    int nextElectionYear = findNextElectionYear(year);
    int dayOn6Nov = getDayOn6November(nextElectionYear);   
    int nextElectionDate = getFirstTuesday(dayOn6Nov);
    printf("The next presidential election day will be Tuesday 11/%d/%d",nextElectionDate,nextElectionYear);
    return 0;
}
