Lập trình tính tổng:
a) T= $\frac{1}{5}$ +$\frac{1}{6}$+… $\frac{1}{99}$ +$\frac{1}{100}$
b)T =$\frac{4}{5}$ +$\frac{5}{6}$+… $\frac{98}{99}$ +$\frac{99}{100}$
c)T= $\frac{6}{5}$ +$\frac{7}{6}$+… $\frac{99}{98}$ +$\frac{100}{99}$
Cái này là lập trình tính tổng T
a)
program a;
uses crt;
var i:integer;
T:real;
begin clrscr;
T:=0;
for i:=5 to 100 do
T:=T+1/i;
write(‘T= ‘,T:4:2);
readln;
end.
b)
program b;
uses crt;
var i,j:integer;
T:real;
begin clrscr;
T:=0;
for i:=4 to 99 do
for j:=5 to 100 do
T:=T+i/j;
write(‘T= ‘,T:4:2);
readln;
end.
c)
program c;
uses crt;
var i,j:integer;
T:real;
begin clrscr;
T:=0;
for i:=6 to 100 do
for j:=5 to 99 do
T:=T+i/j;
write(‘T= ‘,T:4:2);
readln;
end.

*Câu a):
Program tinh_tong;
Uses crt;
Var i: byte;
T: real;
Begin
T:=0;
For i:= 5 to 100 do
T:= T+ 1/i;
Writeln (‘Tong T la:’,T:5:2);
Readln
End.
*Câu b):
Program tinh_tong;
Uses crt;
Var i: byte;
T: real;
Begin
T:=0;
For i:= 4 to 99 do
T:=T+i/(i+1);
Writeln (‘Tong T la:’,T:5:2);
Readln
End.
*Câu c):
Program tinh_tong;
Uses crt;
Var i: byte;
T: real;
Begin
T:=0;
For i:=6 to 100 do
T:=T+i/(i-1);
Writeln (‘Tong T la:’,T:5:2);
Readln
End.
