Question

Extend the program below so that after closing the files, program asks the user to enter a name. The program should store this input as a string, and then search the name array for the ‘search name’ just entered by the user. If the search name is found in the name array, the program will print the name, age and wage corresponding to the search name to the screen. If the search name is not found in the name array, program prints “Name not found” to the screen. The search would need to use string comparison functions.

(b)    #include<stdio.h>
#include<stdlib.h>

char c;
char name[10][50];
int roll[10];
float marks[10];

int main (int argc, char **argv)

 {

    FILE* f;
    if (argc != 2)

 {
        printf("No filename in the argument");
        return 1;
    }
    
    f = fopen(argv[1], "r");   
    if (f == NULL) {
        printf("The file cannot be opened successfully: %s\n",argv[1]);
        return 1;
    }
    printf("The file has been opened successfully\n\n");
    
    int lines = 0;
    while( c != EOF)
    {
        c = fgetc(f); 
        if(c == '\n')

{
            lines++;
        }
        if(c ==EOF)

{
            lines++;
        }

else

{
            printf("%c",c); 
        }
    }
    

    printf("\n\nFile has Total %d Lines.",lines);
    
    //EXTENDED PART
     
    f = fopen(argv[1], "r"); 
    lines=0;
    while( fscanf(f, "%s %d %f\n", name[lines], &roll[lines], &marks[lines]) != EOF )
    { 
        lines++;
    }
    fclose(f);
    char filename[] = "output.csv";
    f=fopen(filename,"w");
    int i=0;
    while(i<lines)

{
    fprintf(f,"%s,%d,%f\n",name[i],roll[i],marks[i]);
    i++;
}
    fclose(f);
    
    return 0;  
}
