convert digits into letters

[mpower17]

hello guys i am trying to convert my 1 into 't' and my 0 into 'f' but so far no luck. Any help will be appreciated. It is a basic truth table. Thank you. Here is the code

#include <string>
using namespace std;
int main()
{
int a,b,c,d,e,f,g,h,i,j,k,l,m;

cout<<"Number 1 refers to True, 0 to False \n\n\nl | m | ~l | ~m | l&&m | l||m | l^m | l^m^m | l^m^l | ~(l&m) | ~l||~m | ~(l||m) | ~l&~m | \n\n"<<endl;

for (l = 1; l >= 0; l--)

for (m = 1; m >= 0; m--){

if ((l == m) || (l = !m) || (!l == m) || (!l == !m))

a = !l, b = !m, c = l&&m, d = m || l, e = l^m, f = l^m^m, g = l^m^l, h = !(l&&m), i = !l || !m, j = !l && !m; k = !(l||m);

cout <<l<<" "<< m<<" "<<a<< " "<<b<< " " <<c<< " "<<d<< " "<<e<< " "<<f<< " "<<g<< " "<<h<< " "<<i<< " "<<k<< " " <<j<<"\n\n"<< endl;
}
system("pause");
return 0;
}

you need brackets after your for and if statements.
