Use comma-separated list expansion. And you need to specify the format only once (see help fprintf)
A = {1 2 3 4}
sprintf('%d ',A{:})

a={1,2,3,4,5};
sprintf('%d,%d,%d,%d,%d',a{:});

mycell = {1,2,3,4,5};
s = sprintf('%d%d%d%d%d', mycell{:})

If using multiple different cells:
%% Edited
% var = {'a','b','c','d','e'};
% num = {1,2,3,4,5};
% s = strjoin(cellfun(@(v,n)sprintf('%s = %d',v,n),var,num,'UniformOutput',false),'; ');

Simpler and more efficient:
>> tmp = [var;num];
>> fprintf('%s = %d\n',tmp{:})
a = 1
b = 2
c = 3
d = 4
e = 5

Oh, when sprintf and fprintf reported:
>> s = sprintf('%s = %d\n',var,num)
Error using sprintf
Function is not defined for 'cell' inputs.
I thougth sprintf and fprintf were not defined for cell arrays.
Edited: (And I did not think about the cell unpacking {:}
Anyways, yours is definitely the better solution!
