Printf prints something to the standard output stream, and scanf inputs something from the standard input stream.
Yes: double d; printf ("scanf's just returned %d\n", scanf ("%lf", &d));
well major difference between scanf and printf is that scanf is an input statment and printf is an output stament scanf is used to take data in from the user and printf is used to display the result on the screen Regards
== == What is printf in c or prototype of printf with example (q) What is prototype of printf function ? Explain each term. Ans: Prototype of printf function is : int printf( const char *format ,…) Explanation of each term : Parameter of printf function is : (three continuous dots) : It is called ellipsis. It indicates the variable number of arguments. Example of ellipsis: #include void ellipsis(int a,...); void main() { int a=5,b=10; clrscr(); ellipsis(a,b); getch(); } void ellipsis(int a,...) { printf("%d ",a); } Output:5 So printf function can have any number of variables as an argument.
#include<stdio.h> Void main() { int a,b; printf("Enter a Number: "); // for print function as an out-put scanf("%d",&a); //for scan function as in input /* Here we can use print function once again as: */ a=a++; printf("%d",a); }
Hiii,scanf() is an predefined function of C to getting runtime input from the user.Syntax:-scanf("sequence specifier",&variable_name);example:-#includevoid main(){int number;printf("\n Enter any number"); //message to userscanf("%d",&number); //getting input from userprintf("\n entered number is %d",number); // displaygetch();}
int printf (const char *fmt, ...)orint scanf (const char *fmt, ...)
The Standard Librarary Function in C is printf,scanf inf Standard input output header.. which is stdio.h.
No, they are variadic.
..use do{} while{}..for example..#includemain(){int choose;double a,b,c;printf("Enter 7 if you want to use the calculator. Otherwise,type any character.\n");scanf("%d",&choose);do{if (choose==7){printf("Press 1 for addition.\n");printf("Press 2 for subtraction.\n");printf("Press 3 for multiplication.\n");printf("Press 4 for division.\n");scanf("%d",&choose);if (choose==1){printf("Enter the addends\n");scanf("%lf %lf", &a,&b);c=a+b,printf("The sum of %lf and %lf is %lf.\n",a,b,c);}else if(choose==2){printf("Enter the minuend and subtrahend\n");scanf("%lf %lf", &a,&b);c=a-b,printf("The difference of %lf and %lf is %lf.\n",a,b,c);}else if(choose==3){printf("Enter the multipliers\n");scanf("%lf %lf", &a,&b);c=a*b,printf("The product of %lf and %lf is %lf.\n",a,b,c);}else if(choose==4){printf("Enter the dividend and divisor\n");scanf("%lf %lf", &a,&b);c=a/b,printf("The quotient of %lf and %lf is %lf.\n",a,b,c);}else{printf("You have entered an invalid digit.\n");}printf("If you want to continue,press 7 and choose again from 1 to 4.\n");printf("Do you want to exit? Enter any key.\n");scanf("%d",&choose);}}while(choose==7);}
do statement; while (condition);ordo { statements } while (condition);
Printf returned no. of character receive . scanf return no of variable to be inputed according to format specifier . eg: i=printf("thisisc") printf("%d",i); //i=7 j=scanf("dd",&a,&b,&c,&d); printf("%d",j); IT IS MOST APPROPRIATE ANSWER FOR THIS Q .......... PLZ DO Practically............
scanf is a function, not a statement. Example: int a; char name[12]; scanf ("%d %s", &a, &name[0]);
