Code:
if(average >= 100) { grade = 'A+' ; }
else if(average >= 90 && average < 100) { grade = 'A' ; }
else if(average >= 80 && average < 90) { grade = 'B' ; }
else if(average >= 60 && average < 80) { grade = 'C' ; }

how to print a multiple characters?
i have a really question that's been bugging me for a little too long now. so i want to print this, where 'grade' is a char
... -
thanks alot!!!! that along with rearranging my loop produced the desired output. this is what the final matric_mult looked like:
...Code:void matrix_mult(double a[3][3], double *b, double *c, int rows) { int k, s, r; double dot_p, res_vec[5]; double w[3], z[3] = { 1./sqrt(3.), -1/sqrt(3.), 1./sqrt(3.) }; for(s=0; s<3; s++) { for(k=0, dot_p=0; k<3; k++) -
thanks for the quick reply.
after doing that, it gives a different value but it is still wrong. any other suggestions??Leave a comment:

C/C++ Matrix/Vector Calculation
Hey, I have a program which is done but it gives me the wrong output. It would be greatly appreciated if somebody could help me get the correct output. The question asks:
Develop a program which computes the current value of the vector {x} based on the following forward iteration: {x}(n+1) = [K] {x}(n)+ {z}, n = 0,1,2,3,4.
In other words, the next vector {x} is equal to the product of [K] and the current vector {x} + constant... -
how to add+multiply matrices
Develop a program which computes the current value of the vector {x}
based on the following forward iteration:
{x}(n+1) = [K] {x}(n)+ {z}, n = 0,1,2,3,4.
In other words, the next vector {x} is equal to the product of [K] and
the current vector {x} + constant vector {z}.

matrix multiplication and addition
The question asks to write a program that computes the following:
{x}(n+1) = [K] {x}(n)+ {z}, n = 0,1,2,3,4.
In other words, the next vector {x} is equal to the product of [K] and
the current vector {x} + constant vector {z}.
[K] is a constant 3x3 matrix defined by:
double k[3][3] = { { 1.2, -3.0, 1.1},
{-4.1, 6.2, -2.2},
{ 3.4, -2.5, -3.3} };... -
thanks alot guys! that helped alot.
turns out my gunc() wasn't properly defined so i ended up computing g(x) directly on f(x)
double func(double x, int n, double K)
{ double factorial, y;
factorial = mfact(n);
y = (1+K*pow(cos(n* x),n))/factorial;
return y; }Leave a comment:

or actually g = 1+K*pow(cos(n*x ),n);Leave a comment:

thanks for the quick reply
so i realized that i was supposed to use pow() for line 73
g = 1+K*pow(cos,n)* (n*x);
and changed m to n but i still get this error so i cant execute the program
error: expected declaration specifiers or '...' before 'main'
>>referencing to line 7Leave a comment:

help with function that calls another function
Write a program which calculates the integral of the function
f(x)=g(x)/n! , where g(x)=1+K*cos^n( n*x)
on the interval from a to b (a<b). In the main program, scanf a
non-negative integer value of n and double values of K, a, and b.
Call the function Integ() to evaluate the integral.
Your main program should be followed by four functions:
double Integ(int n, double... -
Help with sine taylor series
hey guys, the question asks to
Scan the angle in degrees using x=PI*x_deg/180 and calculate Y=sin^2(x).
Calculate sin^2(x) approximately by using n terms (n>0) the Taylor series
sin(x)=Sum[(-1)^k x^(2k+1)/(2k+1)!] (k goes from 0 to n-1)
Scan an integer value of n. Evaluate (2k+1)! by an embedded for-loo statement. Use two do/while statements to continue the calculations for different n and different x_deg.
Calculate...
