fprintf() in C
fprintf is used to print content in file instead of stdout console.
int fprintf(FILE *fptr, const char *str, ...);
Example:
C
// C Program for the above approach #include<stdio.h> int main() { int i, n=2; char str[50]; //open file sample.txt in write mode FILE *fptr = fopen("sample.txt", "w"); if (fptr == NULL) { printf("Could not open file"); return 0; } for (i = 0; i < n; i++) { puts("Enter a name"); scanf("%[^\n]%*c", str); fprintf(fptr,"%d.%s\n", i, str); } fclose(fptr); return 0; } |
