lab4C.c file contains:

#define SIZE 10
#define SIZE2 40

int main(int argc, char *argv[])
{

     char input[SIZE2];    
     char name[SIZE];  
     ....
     char resu[SIZE2], resu2[SIZE2], resu3[SIZE2];
        
     printf("Enter name, age and wage (exit to quit): ");
     fgets(input, 40, stdin);
     while (...)

        /* use fgets to read again */
        printf("Enter name, age and wage (exit to quit): ");
        fgets(input, 40, stdin);
     }

3.1 Specification Develop an ANSI-C program that reads user information from the standard inputs, and outputs the modified version of the records. 3.2 Implementation Download file 1lab4C.c and start from there. Note that the program uses loop to read inputs (from standard in), one input per line, about the user information in the form of name age wage, where name is a word (with no space), age is an integer literal, and wage is a floating point literal. See sample input below. uses fgets () to read in a whole line at a time. An brief introduction to fgets is given in problem D2. The program should, after reading each line of inputs, creates a char [40] string resu for the modified version of the input. In the modified version of input, the first letter of name is capitalized, age becomes age 10, and wage has 100% increases with 3 digits after decimal point, followed by the floor and ceiling of the increase wage. The values are separated by dashes and brackets as shown below then duplicate/copy resu to resu2 using a library function declared in (how about strcpy or strcat?) then duplicate/copy resu to resu3 using a library function declared in (how about sprintf?) then output the resulting strings resu, resu2 and resu3 continue reading input, until a line of exit is entered + Hints: When fgets reads in a line, it appends a new line character \n at the end (before \0) Be careful when checking if the input is exit To tokenize a string, consider sscanf To create resu from several variables, consider sprintf If you use math library functions, be aware that the return type is double 3.3 Sample Inputs/Outputs: red 118 a.out Enter name, age and wage (exit to quit): si Sue-32-66.600- [66, 67] Sue-32-66.600- [66, 67] Sue-32-66.600- [66, 67] ue 22 33.3 age and wage (exit to quit): john 60 1.0 Enter name, John-70-2.000- [2,2] John-70-2.000- [2,2] John-70-2.000- [2,2] age and wage (exit to quit): lisa 30 1.34 Enter name, Lisa-40-2.680- [2,3] Lisa-40-2.680- [2,3] Lisa-40-2.680- [2,3 Enter name, age and wage (exit to quit): judy 40 3.2 Judy-50-6.400- [6, 7] Judy-50-6.400- [6,7] Judy-50-6.400- [6,7] Enter name, age and wage (exit to quit): exit red 119 %
