Enormous Input test Codechef Solution in C language with logic

 Let first we discuss some topic.



Increment and decrement operators

i++  (i is increased by 1)

i--  (i is decreased by 1)

printf(“—i=%d”,--i);

This first decrements i and then prints it

printf(“i--=%d”,i--);

This first prints i and then decrements it

1. +++ operators does not exists => Important

2. += is compound assignment operator just like -=, *=, /= & %= =>Also important


here the code-->

#include <stdio.h> 

int main() {

int n, k;

scanf("%d %d", &n, &k);

int ans = 0;

for (int i = 0; i < n; i++) {

int t;

scanf("%d", &t);

if (t % k == 0) {

ans++;

}

}

printf("%d\n", ans);

return 0;

}

and then use custom input, used data provided by codechef in question.

So now discuss the logic we only need to remove the (" using namespace std; ")

because “using namespace std” means in programming languages we use the namespace named std. “std” is an abbreviation for standard. So that means we use all the things with in “std” namespace. If we don't want to use this line of code, we can use the things in this namespace like this. std::cout, std::endl

so this is the reason you got error in your earlier submission :).

Number mirror Codechef problem Solution in C languages with logic

Let first we some topic Receiving input from the user In order to take input from the user and assign it to a variable, we use scanf function. The syntax for using scanf: scanf("%d",&a); // %d for integer // %f for real constant // %c for character & is the “address of” operator and it means that the supplied value should be copied to the address which is indicated by variable i. Here the code--> #include <stdio.h> int main(void) {     int n;     scanf("%d",&n);     printf("%d",n); return 0; } The logic is very easy that first we declare a integer then take a input through user by using scanf then print that variable.                                                Thank You

ATM CodeChef soultion in C language with logic

first discuss this points because it related to problem Primarily there are 3 types of constant: 1.    Integer constant =    -1,8,9 2.    Real constant =     -322.9,2.5,7.0 3.    Character constant = ‘a’,’$’,’@’(must be enclosed within single inverted commas) For print we use printf("%d",integer_constant); //%d for integer constant  //%f for real constant //%c for character constant So here the code--> #include <stdio.h> int main() { int X; float Y; scanf("%d %f",&X,&Y); if(X%5!=0){     printf("%.2f",Y); } else if(X+0.5>Y){     printf("%.2f",Y); } else{     printf("%.2f",Y-(X+0.5)); } return 0; } so the logic is first we declare variable then we get input by user as you see above through scanf. then their is condition that the atm machine would accept only multiple of five so we use conditional statement that if its not multiple of five and the amount is bigger then Y then its show bal
