- Question
Write a c program to print multiplication table
- Correct Answer
- #include
int main(){ int r,i,j,k; printf("Enter the number range: "); scanf("%d",&r); for(i=1;i<=r;i++){ for(j=1;j<=10;j++) printf("%d*%d=%d ",i,j,i*j); printf("\n"); } return 0; } Sample Output: Enter the number range: 5 1*1=1 1*2=2 1*3=3 1*4=4 1*5=5 1*6=6 1*7=7 1*8=8 1*9=9 1*10=10 2*1=2 2*2=4 2*3=6 2*4=8 2*5=10 2*6=12 2*7=14 2*8=16 2*9=18 2*10=20 3*1=3 3*2=6 3*3=9 3*4=12 3*5=15 3*6=18 3*7=21 3*8=24 3*9=27 3*10=30 4*1=4 4*2=8 4*3=12 4*4=16 4*5=20 4*6=24 4*7=28 4*8=32 4*9=36 4*10=40 5*1=5 5*2=10 5*3=15 5*4=20 5*5=25 5*6=30 5*7=35 5*8=40 5*9=45 5*10=50

Correct Answer: String operations
Explanation:
SNOBOL is a high-level computer programming language used especially in manipulating textual data. It is mainly used for string operations and was developed between 1962 and 1967.
Correct Answer: Prefix Notation: ^ - * +ABC - DE + FG
Correct Answer: 11 2 1 1
Correct Answer: While extracting a float argument using va_arg we should have useed c = va_arg (ptr, double)
Correct Answer: Time and Space
