The getchar() function is used to read a single character from standard input (stdin) and increment the associated file pointer to point to the next character. The return value is an integer which must be cast to a character.
An example demonstrating its usage is shown below.
#include <stdio.h>
int main()
{
char buffer[81];
int i, ch;
for(i=0; (i<80) && ((ch = getchar()) != EOF) && (ch!='\n'); ++i)
{
buffer[i] = (char) ch; // cast input to a character
}
buffer[i] = '\0'; // add null-terminator.
printf( "You entered: %s\n", buffer);
}

What is the meaning of statement missing in function main in c language?
Every C program must have a function, named main(), which is where the program starts execution. If there is no function main(), the computer does not know where to start running the program. The function main() must also do something; if it is just empty, some smarter compilers will note that there is nothing for the program to do, and will give this sort of error message to indicate that you forgot to tell the program what to do.

Here is a program that would calculate the change of a dollar: #include <stdio.h> int main(); { float total=0; float bill=0; float pay=0; printf("How much do you have to pay: "); scanf("%f", &bill); printf("How much did you give out: "); scanf("%f", &pay); total = bill - pay; printf("Your change is: %.2f", total); /*.2 meant 2 digits after the decimal*/ getchar(); getchar(); /*I use getchar(); to pause the program till you press 'enter'*/ return 0; } Here is the program running: How much many do you have to pay: 5.64 /*5.64 is user input*/ How much many did you give out: 4.72 /*You can redo the questions if need be*/ Your change is: 0.92 /*This is where you press 'enter' to close the program from the getchar();*/ I hope this helped :D
