Using the repeated feature of fprintf() function in MATLAB, your program must display the results in the following format:
The force in link (I)= XXXX.XX N
The force in link (I)= XXXX.XX N The force in link (-)= ------- N
-------------------------------
Where I refers to the link number (1-8) in format %i and XXXX.XX is the corresponding force value in that link in %g format.

No loop is required:
>> x = 1:8;
>> y = exp(x);
>> fprintf('The force in link (%d)= %g N\n',[x;y])
The force in link (1)= 2.71828 N
The force in link (2)= 7.38906 N
The force in link (3)= 20.0855 N
The force in link (4)= 54.5982 N
The force in link (5)= 148.413 N
The force in link (6)= 403.429 N
The force in link (7)= 1096.63 N
The force in link (8)= 2980.96 N
Or using %f format:
>> fprintf('The force in link (%d)= %4.2f N\n',[x;y])
The force in link (1)= 2.72 N
The force in link (2)= 7.39 N
The force in link (3)= 20.09 N
The force in link (4)= 54.60 N
The force in link (5)= 148.41 N
The force in link (6)= 403.43 N
The force in link (7)= 1096.63 N
The force in link (8)= 2980.96 N

Please refer the below documentaion to understand the uses of fprintf function
Also, I have written the below code to print the value of at the values x=1:8 using for loop. You can refer this code and make changes as per your requirements.
clc
clear all
for x=1:8
fprintf('The value in link(%d)=%4.2f N\n \n',x,exp(x))
end
