# Multiple conditions for if statement in C / C++

When working with `if` statement in C / C++, we often wonder that "Can `if` statement have 2 conditions?" or "Can you have 3 conditions in an `if` statement?". So in this tutorial, we will learn if an `if` statement can have multiple conditions.

For example: Check if a number N is between 1 and 100?

Explain: Here, we have two conditions, `N > 1` and `N < 100`. So in the `if` statement, we need to use these two conditions.

The best way: Use the "AND" operator to combine two conditions.

```if(N > 1 && N < 100){
cout<<N<<" > 1 and "<<N<<" < 100.";
}```

In some cases, we need to use 2 - 3 or more conditions in the `if` statement. So what are the ways to do that? Let's get started!!

## Multiple conditions for if statement in C / C++

In the `if` statement, we can use many different conditions at the same time. However, we need to use additional operators like: And (&&), Or (||). Now, let's find out each way with us.

### Use the "AND" operator for multiple conditions

Let's say we have 2 conditions in an `if` statement and all of these conditions need to be checked. Then using the "AND" operator is the best solution. Let's see the example below:

Example: assigning grades (A, B, C) based on marks obtained by a student.

• If the percentage is above 90, assign grade A.
• If the percentage is above 75 and below 90, assign grade B.
• If the percentage is above 65 and below 75, assign grade C.
• if the percentage is below 65, assign grade D.

C++ programming:

```#include <iostream>
using namespace std;
int main() {
int score;
do{
cout<<"Enter your percentage: ";
cin >> score;
if(score < 1 || score > 100)
cout<<"\nPlease enter numbers from 1 to 100!!\n\n";
}while(score < 1 || score > 100);

if(score >= 90)
cout<<"Your score is A";
else if(score < 90 && score >= 75)
cout<<"Your score is B";
else if(score < 75 && score >= 65)
cout<<"Your score is C";
else
cout<<"Your score is D";

cout<<"\n-------------------------------\n";
cout<<"This program is posted at learnnc.com";
return 0;
}```

C programming:

```#include <stdio.h>

int main(void) {
int score;
do{
printf("Enter your percentage: ");
scanf("%d", &score);
if(score < 1 || score > 100)
printf("\nPlease enter numbers from 1 to 100!!\n\n");
}while(score < 1 || score > 100);

if(score >= 90)
printf("Your score is A");
else if(score < 90 && score >= 75)
printf("Your score is B");
else if(score < 75 && score >= 65)
printf("Your score is C");
else
printf("Your score is D");

printf("\n-------------------------------\n");
printf("This program is posted at learnnc.com");
return 0;
}```

Output: ### Use the "OR" operator for multiple conditions

In this case, we have two conditions. However, as long as one of them occurs, the block of code inside the `if` statement body must execute. Then we will use the "OR" operator.

Example: Ask the user to enter the natural number N. If `N < 1` or `N > 100`, the message "You entered wrong!!!"

C++ programming:

```#include <iostream>
using namespace std;
int main() {
int score;

cout<<"Enter your percentage: ";
cin >> score;
if(score < 1 || score > 100)
cout<<"\nYou entered wrong!!!\n\n";
else
cout<<"\nYou entered right!!!\n\n";

cout<<"\n-------------------------------\n";
cout<<"This program is posted at learnnc.com";
return 0;
}```

C programming:

```#include <stdio.h>

int main(void) {
int score;

printf("Enter your percentage: ");
scanf("%d", &score);
if(score < 1 || score > 100)
printf("\nYou entered wrong!!!\n\n");
else
printf("\nYou entered right!!!\n\n");

printf("\n-------------------------------\n");
printf("This program is posted at learnnc.com");
return 0;
}```

Output: ### Use the nested if statement for multiple conditions

In addition to using the "And" operator, we can use nested `if` statements with multiple conditions.

Example: Check if a number is between 1 and 100?

C++ programming:

```#include <iostream>
using namespace std;
int main() {
int N;
cout<<"Enter number N: ";
cin >> N;
if(N > 1){
if(N < 100){
cout<<N<<" > 1 and "<<N<<" < 100.";
}
else
cout<<"\nYou entered wrong!!!\n\n";
}

cout<<"\n-------------------------------\n";
cout<<"This program is posted at learnnc.com";
return 0;
}```

C programming:

```#include <stdio.h>

int main(void) {
int N;
printf("Enter number N: ");
scanf("%d", &N);
if(N > 1){
if(N < 100){
printf("%d > 1 and %d < 100.",N,N);
}
else
printf("\nYou entered wrong!!!\n\n");
}

printf("\n-------------------------------\n");
printf("This program is posted at learnnc.com");
return 0;
}```

Output:
