## Write a C program to find the first n prime numbers

Write a C program to find the first n prime numbers, In this C program example, we will learn Algorithm and C Code to find first n prime number.

# Algorithm to find the first n prime numbers

• Declare three variables.
• Take an input.
• Take two for loop and in 2d loop take two if condition, first one for condition and break and the second one for print with an appropriate message.

# C program to find first n prime numbers

```#include<stdio.h>
void main (){
int i,n,j;
printf("enter number:");
scanf("%d",&n);
for(i=2;i<=n;i++){
for(j=2;j<=i;j++){

if(i%j==0){
break;
}
}
if(i==j){
printf("%d\n",i);
}

}
}
```

#### Sample input

Enter any value: 25

# Explanation of this C program

step 1: Start.

Step 2: Create a header file and include a library on file.

Step 3: Create a void main function.

Step 4: Declare three variable (i,n,j).

Step 5: Then create an input with the help of scanf for taking value from the user to find first n prime number.

Step 6: Create two for loop and give conditions.

Step 7: In the loop create two if statements one for cheak condition and brack it and the second one for print the first n prime number.

Step 8:  End.

# Output In this way, we learned how to write a C program to find the first n number.
