(1+2+3.....n) Sum of n natural numbers, (1^2 + 2^2+3^2 ...... n^2)Sum square of n natural numbers, Sum cube of n natural numbers program in C language .

  Natural numbers program in c language      

         How to make (1+2+3.....n) Sum of n natural numbers, (1^2 + 2^2+3^2 ...... n^2)Sum square of n natural numbers, Sum cube of n natural numbers program in C language. Then today we will know about it through this program ...

   Sum of n natural numbers 

        The Sum of n natural number formula are 1+2+3+....n = n(n+1)/2=(n^2+n)/2. The math.h header file is used in this program because the pow() function is defined in this header file. The function pow() syntax is double pow(double a , double b). The double is a data type in c language and it's also defined as %lf for input. In this program add= (k+x)/2 where are k=n^2 ,x=n.



Output is :

ENTER THE NATURAL NUMBER:6
SUM OF  N NATURAL NUMBER:21


 Sum square of n natural numbers :
        The Sum square of n natural number formula is 12+22+32…….n2 = n(n+1)(2n+1)/6 = (2n3+3n2+n)/6. In this program add= (q+w+x)/6; where are q=3n2, w=2n3 and  x=n.




Output is :

ENTER THE NATURAL NUMBER:4
SUM SQUARE OF  N NATURAL NUMBER:30

Sum cube of n natural numbers :

The Sum cube of n natural number formula is 13+23+33 +…..n3 = [n(n+1)/2]2 or =[(n2 +n)/2]2.In this program add= pow(q,y);  y=2, q = (k+x)/2,and[{ x=n,k=n2 }].







Output is :

ENTER THE NATURAL NUMBER:4
SUM CUBE OF NATURAL NUMBER:100

Two dimensional array in C language or matrix program in c language

 Two dimensional arrays: 1.Two dimensional array is known as matrix. 2.An array with two subscripts is termed as two-dimensional array. 3.We know that a one dimensional array can store a row of elements, so a two-dimensional array enables us to store multiple roes of elements. The syntax of declaring a two-dimensional array is : Data-type array name[row][column]; For reading value : for(k=0;k<4;k++) { for(l=0;l<3;l++) { scanf("%d",&a[k][l]); } } For displaying value : for(k=0;k<4;k++) { for(l=0;l<3;l++) { printf("%d",a[k][l]); } printf("\n"); } Simple Matrix Program : #include"stdio.h" int main() { int a[3][3]; int k,l; printf("Enter the array elements: \n"); for(k=0;k<3;k++)  //for reading value// { for(l=0;l<3;l++) { printf("Enter a[%d][%d] :",k,l); scanf("%d",&a[k][l]); } } printf("\n\nMatrix are: \n"); for(k=0;k<3;k++)  //for displaying value...

Arithmetic program in C language || Calculator program in C language

  Calculator  program in C language .           First of all let us know its logic .how is this working . Now let's see it's process . In C language , %d is used to define it's integers and %f is used to define it's floats. In C language , the (+) sign is used as a plus , the (-) sign used as a minus , the (*) sign is used for multiplies and the (/) sign is used for division.                %0.2f it means any float value like 52.987 = 52.98.it show only 2 place of the decimal. PROGRAM                          /*ARITHMETIC PROGRAM IN C LANGUAGE*/ #include"stdio.h" int main() { float a,b,sum,sub,mult,div ; char sign; printf("SELECT ANY SIGN (+ - * / ) :"); scanf("%c",&sign); printf("ENTER THE FIRST NUMERIC VALUE:"); scanf("%f",&a); printf("ENTER THE SECOND NUMERIC VALUE:"); scanf("%f",&b); switch(sign) { case '+':...

Matrix Addition and subtraction program in C language

  Matrix Addition and Subtraction program in C language Today here you will be able to learn about multiple tasks in Matrix-like addition, subtraction, and multiplication. @#1.Matrix Addition   Suppose that we have two matrices of 3X3 orders. This matrix A and B. In this program   C is the addition of A & B; i and k are used for initialization. Matrix Addition Program  #include"stdio.h" int main() { int A[10][10],B[10][10],C[10][10],i,k,row,col; printf("Enter The Matrix row & col = "); scanf("%d %d",&row,&col); printf("Enter the First matrix :\n"); for(i=0;i Output is:  Enter The Matrix row & col = 2 3 Enter the First matrix : Enter matrix[0][0]=2 Enter matrix[0][1]=1 Enter matrix[0][2]=3 Enter matrix[1][0]=6 Enter matrix[1][1]=54 Enter matrix[1][2]=7 First matrix are: 2       1       3 6       54      7 Enter the Second matrix : Enter matrix[0][0]=8 Enter matrix[0][1...
