aoa!
umeed hai tamam members kheriat se hon gay.Mujhay Gw basic ka kuch puchna hai.Array k aik program ki smaj nahi aa rahi k ye run kesay ho ga.Mujhay pata hai k output kia aay gi but step by step kis tarha program execute ho ga ye logic nahi smaj aa rahi.Kisi ko Gw basic ati hai to plz zara is program ko explain kar dain.
10 DIM A(2,2), B(2,2), Z(2,2)
20 FOR R= 1 TO 2
30 FOR C= 1 TO 2
40 READ A(R,C), B(R,C)
50 Z(R,C)=A(R,C)+B(R,C)
60 PRINT Z(R,C)
70 NEXT C
80 PRINT
90 NEXT R
100 DATA 8,4,3,5
110 DATA 6,4,5,5
120 END
RUN
12 8
10 10
Lain bhai ye tha program and output bhi bata di hai.Kisi ko step by step running smaj aa rahi hai to bata dain plz.
jazakALLAH!

10 DIM A(2,2), B(2,2), Z(2,2) //2x2 ki arrays: A, B aur Z
20 FOR R= 1 TO 2 //Outer For loop jo Next R pay khatam hota hay
30 FOR C= 1 TO 2 //Inner For loop jo Next C pay khatam hota hay
40 READ A(R,C), B(R,C) //Neechay DATA say bari bari arrays mein READ kernay kay liyay
50 Z(R,C)=A(R,C)+B(R,C) // Array A aur B kay elements position wise bari bari Add ker kay Z mein store.
60 PRINT Z(R,C) //Oper walay result ko print kerna
70 NEXT C //End of Inner For loop, add 1 to C
80 PRINT // Go to next line for printing
90 NEXT R //End of Outer For loop, add 1 to R
100 DATA 8,4,3,5
110 DATA 6,4,5,5
120 END //End of program
RUN //Run program
12 8 //Output
10 10 //Output

Ji tu pehlay Outer For loop chala. R=1 ho gaya.

Inner For loop chala. C=1 ho gaya.
READ nay A(1,1) pay 8 rakha aur B(1,1) pay 4 rakha. Tu Z(1,1) pay 8+4=12 hova.
PRINT nay Z(1,1) jo kay 12 tha print ker dia
C mein 1 add kia. ab C=2 ho gaya aur wapis Inner For loop pay (line 30)
READ nay A(1,2) pay 3 rakha aur B(1,2) pay 5 rakha. Tu Z(1,2) pay 3+5=8 hova.
PRINT nay Z(1,2) jo kay 8 tha print ker dia
C mein 1 add kia. ab C=3 ho gaya aur wapis Inner For loop pay (line 30)
Ab C ki value 2 say bari ho chuki hay tu Inner For loop nahi chalay ga, tu line 80 pay
PRINT agli line pay cursor lay gaya.

R mein 1 add hova, R=2 ho gaya, aur wapis Outer For loop (line 20)

Inner For loop chala. C=1 ho gaya.
READ nay A(2,1) pay 6 rakha aur B(2,1) pay 4 rakha. Tu Z(2,1) pay 6+4=10 hova.
PRINT nay Z(2,1) jo kay 10 tha print ker dia
C mein 1 add kia. ab C=2 ho gaya aur wapis Inner For loop pay (line 30)
READ nay A(2,2) pay 5 rakha aur B(2,2) pay 5 rakha. Tu Z(2,2) pay 5+5=10 hova.
PRINT nay Z(2,2) jo kay 10 tha print ker dia
C mein 1 add kia. ab C=3 ho gaya aur wapis Inner For loop pay (line 30)
Kionkeh C ki value 2 say bari ho chuki hay tu Inner For loop nahi chalay ga, tu line 80 pay
PRINT agli line pay cursor lay gaya.

R mein 1 add hova, R=3 ho gaya, aur wapis Outer For loop (line 20)
Kionkeh R ki value 2 say bari ho chuki hay tu Outer For loop nahi chalay ga, tu line 100 pay
Phir END, matlab program khatam.

Aur Akhir mein program ki output.
