Dear,

Just made one modification to the above program , at the input file path instead of "a:myfile.txt" created myfile.txt in the working directory of visual stdio.

#include<stdio.h> int main() { FILE *infile; FILE *outfile; int age; char name[20]; infile=fopen("myfile.txt","r"); outfile=fopen("dupfile.dat","w"); if(infile==NULL) printf("files does not exist \n"); else printf("program execution successful \n"); while(fscanf(infile,"%s%d",name,&age)!=EOF) { fprintf(outfile,"%s\t%d\n",name,age); } fclose(infile); fclose(outfile); return(0); }
