Extend the following program so that it uses getchar (only) to read and interpret floating point literals

#include

#define SIZE 50 // assume no more than 50 literals in input

int main(){

int c;

int value;

int resu[SIZE];

int negative;

int index = 0;

int i;

value = 0;

c = getchar();

while ( c != EOF){

if (c=='-'){

negative=1;

}

else if (c == ' ' || c == ' ')

{

if(negative==1){

value = -value;

}

resu[index] = value;

index++;

value=0;

negative=0;

}

if(c >= '0' && c <= '9')

value = value*10+(c-'0');

c = getchar(); // read next

}

printf("-------- ");

for(i=0;i

printf("%d\t%d ", resu[i],resu[i] *2);

return 0;

}

• should use getchar() to read inputs (from standard in) until EOF is read. The input contains floating point literals and integer literals separated by one blanks or new line characters. The program interprets each literal and put into an float array. When end of file is reached, the program prints out the value of each float as well as the value multiplied by 2, as shown in sample output below.
• assume all floating point literals are valid float/double or int literals (both 2.3, 5, .4 are considered valid). There are no negative numbers.
• should not use other input IO functions such as scanf(), fgets(). Only getChar() is allowed to read input. (So have to read char by char.)
• should not use other library function such as atoi(), atol(), atof(), strtol(), strtoul(). (So have to convert manually)
